ThruDark Review: Is This Ex-Special Forces Brand Worth It?

Every ThruDark review I could find before writing this one was either a Trustpilot page, a coupon site, or a write-up of a single flagship jacket sent to the reviewer by the brand. Nobody has answered the question people are actually typing: is ThruDark worth it, across the range, judged by someone who paid for the kit?

That is what this is. I own four ThruDark pieces, all bought at retail with my own money: the Phalanx Fleece, the Black Ops Dyneema Jumper, an Insignia long-sleeve tee and a Black Mark tee. I also live in Dorset, which happens to be where ThruDark is based. Their head office and their Unit Four store are in Poole, about half an hour from my front door, and the coastline they photograph their kit on is the coastline I hike every week. A Dorset brand, reviewed by a Dorset site, on Dorset trails.

The founders' military records are real, verified and decorated, and I will report them accurately. But a service record does not keep you warm on the Purbeck ridge in February. The clothing has to do that on its own, so the clothing is what gets judged here.

The verdict up front

ThruDark makes very good clothing at prices that include a premium for the story. Both halves of that sentence are true and neither cancels the other out.

The quality is real. The fabrics are the same premium names the established technical brands use: Polartec, Pertex, eVent, PrimaLoft. The construction on the pieces I own is excellent, and the brand is unusually honest about its own products, publishing ratings like a 2/10 for wind resistance on its best-known fleece rather than pretending everything does everything.

The premium is also real, and it is worth understanding what it is made of. You are paying for genuinely technical fabrics, European manufacture, a warranty the brand honours, and a story that has the unusual virtue of being verifiably true. What ThruDark offers is a particular combination: technical kit in designs you can wear off the hill, built to a standard that has held up well in my experience, from a brand whose origin is fact rather than marketing invention.

If the design, the story and the everyday-to-mountain crossover appeal to you, ThruDark will not disappoint on quality. The Phalanx Fleece is the piece I would start with, and the Black Ops jumper is the affordable way to find out whether the brand is for you.

Who are ThruDark?

ThruDark was founded by Anthony "Staz" Stazicker and Louis Tinsley, both former members of the Special Boat Service. Between them: 27 years in the British military, 18 of those in UK Special Forces. Staz served around ten years in the SBS as a sniper instructor and demolitions expert and was awarded the Conspicuous Gallantry Cross, second only to the Victoria Cross. The two met in 2006 on a mountain training exercise.

The company was incorporated in 2016 in Poole, Dorset, where it is still headquartered. Louis left the forces in 2017 and started building the brand while Staz was still serving; Staz left in 2018 and ThruDark launched publicly in May that year at watchmaker Bremont's London HQ, with a launch film narrated by Tom Hardy.

The name comes from working through darkness on night operations, and from enduring dark times. The motto is "Endeavour Through Adversity". Ambassadors have included Victoria Pendleton, Jason Fox, Ollie Ollerton, Aldo Kane and Lizzie Daly.

That is the heritage, and it deserves to be reported straight. Whether it justifies the prices is a separate question, answered further down.

The Everest chapter

The moment that put ThruDark on the map was Nims Purja's Project Possible in 2019. ThruDark equipped the expedition, and a bespoke ThruDark summit suit went up Everest during Nims' record-breaking run at the world's 8,000-metre peaks.

For a brand barely a year out of launch, kitting one of the most publicised mountaineering projects of the decade was an extraordinary credential, and it remains the strongest evidence that ThruDark's technical kit works at serious altitude. One thing to be clear about: this is a chapter in the brand's history, not a current partnership. Nims has since launched his own apparel line, so ThruDark's association with him is past tense.

The years since have added quieter but more relevant milestones for UK hikers. The Force activewear range arrived in 2020. In 2022 the Centurion Alpine jacket won Polartec's Apex award, which is peer recognition from the fabric maker itself, not a marketing gong. In 2023 the brand went into Selfridges, and in 2024 it opened Unit Four, its own retail space in Poole, in what used to be its headquarters.

What the kit is actually made of

Strip away the branding and ThruDark's material choices are what tell you whether this is a serious technical clothing company or a merchandise operation. The short answer: the fabric list reads like a technical brand, not a lifestyle one.

The waterproof stack: Pertex Shield and eVent, not GORE-TEX. This is ThruDark's most interesting decision. There is no GORE-TEX anywhere in the range. Their hardshells use Pertex Shield 3-layer fabric (the £450 Mountain Pro runs a 20,000mm hydrostatic head) and eVent DV Alpine on the Aigis and Skirmish shells. That is a deliberate route around the default choice, and it is not a compromise: Pertex Shield appears on plenty of respected jackets, including several in our spring waterproof jackets guide, and eVent has long been rated for breathability by people who sweat uphill for a living. You lose the reassurance of the most famous name in waterproofing. You do not lose waterproofing.

Insulation and fleece. Polartec runs through the mid layers: High Loft in the Phalanx Fleece, plus Alpha, Thermal Pro, Power Grid, Power Stretch and others across the range. Synthetic insulation is PrimaLoft, including Gold Active Plus and the aerogel-infused Cross Core. These are the same fills you find in kit from the biggest technical names, and they behave the same way here.

Durability layers. Dyneema, a fibre the brand quotes as 15 times stronger than steel by weight, shows up as reinforcement: shoulder panels on the Mountain Pro, elbow panels on the Black Ops jumper. CORDURA and NyCo ripstop cover abrasion zones elsewhere.

The exotic stuff. The Veles softshell uses a graphene-enhanced fabric, with claims around abrasion resistance and thermal conductivity. Those are the brand's claims, and graphene clothing is still a young technology, so treat them as promise rather than proven.

The unglamorous details. Polygiene anti-odour treatment, RECCO avalanche reflectors in the mountain kit, YKK zips throughout, Cohaesive cord adjusters, and British Millerain waxed cotton on the heritage pieces. Small things, but they are the choices of a company specifying components properly rather than hitting a price point.

One caveat on provenance, because the marketing photography can mislead: this is not "made in Britain" clothing. ThruDark kit is designed in Poole and made in European facilities, in Italy, Portugal or Turkey depending on the garment. My Phalanx is made in Portugal; the current Black Ops jumper is made in Turkey. European manufacture at this quality level is normal and nothing to apologise for, but you should know what you are buying.

The range, mapped: £50 to £450

ThruDark's range is wider than the summit-suit imagery suggests, and it helps to see it as three tiers.

At the bottom, the Insignia tee is £50 for a heavyweight 250gsm cotton t-shirt. The Black Ops Dyneema Jumper is £130. These are the pieces most ThruDark customers actually buy, and they are closer to premium streetwear pricing than outdoor pricing.

In the middle sit the technical mid layers: the Phalanx Fleece at £240 and insulated pieces like the Engage at £375. This is where ThruDark asks you to pay technical-flagship money for mid-layer categories, and it is where the worth-it question gets sharpest.

At the top, the Mountain Pro Waterproof is £450: Pertex Shield 3L, Dyneema-reinforced shoulders, RECCO reflector. That is serious hardshell money, and it is specced like a serious hardshell.

Alongside all of this runs Force, the gym and training range launched in 2020, plus purpose-built collections for skiing (Ronin), mountaineering and contact sports. The site merchandises by pursuit, which tells you who the brand thinks its customer is: someone who trains, hikes and lives in the same wardrobe.

Where to buy is simple, because the list is short: ThruDark's own site, their Unit Four store in Poole, and Selfridges. There is no Amazon presence at all, so any "ThruDark" listing you find there deserves suspicion.

New for 2026: the Pinnacle, ThruDark's first hiking pack

Everything above is clothing, and clothing is where ThruDark built its name. In 2025 it did something more interesting for us: it moved into hiking backpacks. The Pinnacle is its first proper hiking pack, in two sizes, a 28L for day walks and a 42L for overnights and multi-day trips.

The Pinnacle is ThruDark's flagship shell, and what follows is a first look at what they have built. A full hands-on review, tested on the Jurassic Coast and the Purbeck hills where I put everything else through its paces, will follow.

Pinnacle 28L

£160, 1.2kg, day walks and fast days, load-tested to 13kg, 60mm back adjustment

Pinnacle 42L

£190, 1.7kg, overnights and multi-day, load-tested to 14kg, 75mm back adjustment

Main fabric

210D recycled Robic polyamide with a C0 DWR finish

Reinforcement

840D ballistic nylon at the base and wear points

Both include

detachable rain cover, adjustable back system, YKK zips, hydration sleeve, pole and hip-belt attachments

Backed by

ThruDark's 5-year warranty and lifetime repair

On paper it reads exactly as you would expect from this brand: a recycled main fabric to keep the weight sensible, then ballistic nylon armoured onto the base and corners where packs actually wear through. That is the ThruDark pattern, specify properly and reinforce the failure points, applied to a rucksack. The load ratings (13kg on the 28, 14kg on the 42) are honest real-world numbers rather than headline figures, and a proper detachable rain cover is included rather than sold as an extra.

The obvious question is whether an ex-Special-Forces clothing brand can build a pack to rival Osprey or The North Face at this money, and that is exactly what I want to answer on the hill rather than from a spec sheet. For now it is a genuinely promising British option, and the piece I am most curious about in the whole range.

Where to buy: direct from ThruDark, the Pinnacle 28L at £160 and the Pinnacle 42L at £190, in Obsidian Black or Olive Green.

What I own and how it's held up

Everything below was bought at retail. ThruDark has never sent me anything, and no link on this page earns me a penny.

ThruDark Phalanx Fleece (non-hooded, black, medium)

Price

£240

Body fabric

Polartec High Loft

Panels

Polartec Power Grid underarms

Details

YKK zips, thumb loops, hook-and-loop insignia patches

Fit

Regular

Made in

Portugal

The Phalanx is ThruDark's longest-serving design, in the range since 2019, and the piece Polartec themselves feature. The High Loft body is the warm, lofted fleece; the Power Grid underarm panels are there to dump heat when you are moving. ThruDark's own ratings give it 8/10 for warmth, 8/10 for breathability and 2/10 for wind resistance, and that last number is honest: this is a static-warmth and layering piece, not a windproof outer.

Mini-verdict: the best thing ThruDark makes for a hiker and the piece that best defends its price tag. Full detail in the ThruDark Phalanx Fleece review.

ThruDark Black Ops Dyneema Jumper (Generation 2, black, medium)

Price

£130 (current generation)

Fabric

500gsm brushed-back premium cotton

Reinforcement

Dyneema and Cordura hexagonal-weave elbow panels

Details

Rib cuffs and hem

Fit

Regular

A very heavy cotton sweatshirt with Dyneema in the elbows. Mine is the second generation, with the hexagonal-weave Dyneema and Cordura elbow panels; the current third generation keeps the Dyneema-reinforced elbows in a revised construction and is made in Turkey. At 500gsm this is roughly twice the fabric weight of a standard high-street sweatshirt, and you feel it the moment you pick it up.

Mini-verdict: the cheapest way into the brand that still feels like the brand, and the piece I would point most people at first. Whether Dyneema elbows on a sweatshirt are engineering or storytelling gets a full answer in the Black Ops Dyneema Jumper review.

ThruDark Insignia long-sleeve tee (navy, medium)

Price

Insignia range from £50

Fabric

Heavyweight premium cotton

Details

Rubberised chest and arm insignia, underarm vent holes

Fit

Regular

The Insignia range is ThruDark's everyday baseline: heavyweight cotton tees with the brand's insignia on the chest and left arm, plus a detail you do not expect on a casual tee, small vent holes under the arms. The short-sleeve version is £50 for 250gsm cotton, which is thick by t-shirt standards.

Mini-verdict: a well-made heavyweight tee at a price where good menswear brands also live. You are paying for fabric weight and finish, and you get both. No separate review planned; this is the whole verdict.

ThruDark Black Mark tee (grey, medium)

Fabric

290gsm premium cotton

Details

High-build chest print, branded neck taping, underarm vent holes

Fit

Regular

The Black Mark is the Insignia tee's heavier sibling: 290gsm cotton with a raised chest print and taped neck seam. The name comes from the mark handed to condemned pirates, which is the kind of flourish ThruDark enjoys and your mileage on that will vary.

Mini-verdict: the same story as the Insignia in a heavier weight. If you only buy one ThruDark tee, buy whichever cut you prefer; the quality is consistent across both. Reviewed in full right here, nowhere else.

Sizing: how ThruDark fits

The official line is true to size, and the brand's product pages state a regular fit on most pieces, including everything I own. All four of my pieces are a medium, which is my regular size across Rab and Patagonia.

Two structural points hold regardless of my measurements. First, the heavyweight cotton pieces (Black Ops, Insignia, Black Mark) do not have the stretch of a technical fabric, so if you sit between sizes the fabric will not rescue a tight choice. Second, if you plan to wear the Phalanx as a mid layer under a shell, the regular fit is cut for that job, so resist the urge to size up.

ThruDark publishes a full size guide with garment measurements on every product page, and with no high-street stockists beyond Selfridges and their Poole store, checking it before ordering is worth the two minutes.

Is ThruDark worth the money?

Here is the straight answer, in three parts.

On quality, yes. The four pieces I own are made to a high standard, the fabric choices are legitimate rather than name-dropping, and the brand's willingness to publish unflattering numbers about its own products (that 2/10 wind rating) is rarer than it should be in this industry. Nothing I own from them has given me a reason to doubt the construction.

On performance, yes. The kit does what it claims. The fabrics are the real thing, the construction backs them up, and the brand's own product pages tell you honestly what each piece is and is not built for, which means you can buy the right tool and get exactly what you expected. The Everest chapter was not achieved in marketing copy.

On the whole package, it depends what you are buying. This is premium kit at premium prices, and part of what you are paying for is the story: the SBS heritage, the Everest chapter, the Tom Hardy launch film, the insignia on the chest. That is not a scam, it is how premium brands work, and ThruDark's story has the unusual virtue of being verifiably true. You are also buying design that moves between the trail, the gym and the pub without looking like it is cosplaying any of them, which almost no purely technical brand manages.

So: worth it if the quality, the crossover design and the brand mean something to you, and you buy the right pieces for the right jobs. Start with the Black Ops jumper or a tee to test the water, and make the Phalanx your first technical purchase.

ThruDark discounts that actually exist

Search for ThruDark discount codes and you will drown in coupon sites promising 30% off. Nearly all of it is junk: expired codes, made-up codes, or newsletter offers dressed up as exclusives. Here is what actually exists.

15% for military, NHS, emergency services and teachers. ThruDark runs a verified industry discount through its own site covering serving and former military, NHS staff, emergency services and teachers. Given the brand's origins this is the discount they treat seriously, and if you qualify it is the best legitimate price you will get.

10% for newsletter sign-up. The standard first-order discount for joining their mailing list, direct from the brand.

Beyond those two, do not build a purchase plan around waiting for a sale. There is no reliable discount calendar, and no third-party retailer discounting except whatever Selfridges chooses to do. My advice is simple: sign up for the 10%, claim the 15% if you are entitled to it, and ignore every coupon site result entirely.
