Rab Torque Vapour-Rise Pants review: the winter mountain trouser built winter-first

Most winter hiking trousers are three-season trousers with a brushed inner face. The Rab Torque Vapour-Rise Pants are not. Rab designed this trouser winter-first, for winter walking, scrambles and fast-moving ascents, and every feature on it answers a specific cold-weather problem: a zoned wicking lining instead of a sweaty fleece one, thigh vents for the climbs, reinforced knees for rock and crampon scuffs, and ankle zips that open over a winter boot.

That focus is why it took the winter mountains slot in our best winter hiking trousers guide, and it is why, when I put together the kit list for a Nordic winter trip, this is the trouser I chose. After comparing everything on the UK market at quality level, the Torque Vapour-Rise was the pair whose spec sheet reads like it was written by someone who actually spends winter on a hill.

Who this trouser is for

This trouser is for: winter hillwalkers and mountaineers whose season includes the Brecon Beacons, Snowdonia or the Scottish hills in proper conditions. People who work hard uphill and then stand still on a summit in a freezing wind, which is exactly the temperature swing the zoned lining is designed around. Scramblers who want reinforced knees and a stretch fabric that moves. Anyone heading somewhere seriously cold, which is precisely why it made my own Nordic kit list.

This trouser is not for: low-intensity cold-weather walking, where a £165 breathable mountain trouser is wasted and a budget fleece-lined pair does the job for a third of the price. Three-season walkers, who should be looking at the Montane Terra instead. And anyone who wants one warm trouser for ordinary UK winter days rather than mountain routes: the Salomon Wayfarer Warm covers that brief for £55 less, and I compare the two below.

What Vapour-Rise actually is

Vapour-Rise is Rab's name for its lined softshell construction, and it is worth decoding because the label confuses people into expecting a fleece lining. It is not one.

The system pairs two layers. The outer is Rab's Matrix stretch double weave, a 133gsm woven softshell face with a fluorocarbon-free DWR that sheds drizzle, dew and dry snow. Inside sits the Vapour-Rise lining, and this is the clever part: it is zoned, so it puts enhanced warmth where you need it and expels moisture from high heat areas rather than trapping it.

That zoning solves the problem that kills most warm trousers on a real hill day. Legs working uphill produce serious heat. A uniform fleece lining holds all of it, you finish the climb damp, and then the damp freezes you on the descent or the summit stop. A wicking, zoned lining takes the edge off the cold without turning the climb into a sauna. It is the difference between a trouser designed for moving in winter and a trouser designed for standing around in it, and Rab is one of the few brands doing it properly at the legs. For more on where the brand sits, our Rab brand spotlight covers the full range.

Warmth and moisture management

Rab files this trouser under hill walking, mountaineering and trekking, and the warmth level is calibrated for exactly that: enough insulation to hold off a winter wind on exposed ground, not so much that a 400m ascent becomes unbearable.

The double weave outer does a lot of the work. Dense woven softshell faces are what actually keeps legs comfortable on UK hills, because wind is the real enemy here. A 6C day in a 40mph ridge-top wind cuts through an unlined summer trouser completely, and a fabric that kills the wind is worth more than an extra millimetre of lining.

The lining then handles the part most winter trousers get wrong: sweat. On a hard climb the zoned construction moves moisture out of the high-output areas, so you arrive at the top of the pull dry rather than damp. On the coldest days, thermal leggings underneath extend the system further, and the regular fit leaves room for that layer.

The winter details: vents, ankles, reinforcement

Three features separate this from a generic lined trouser.

Zipped thigh vents. When the gradient bites and even a zoned lining is too much, the vents dump heat directly. This is standard on quality ski wear and rare on hiking trousers, and it is the feature that lets one trouser span a freezing car park start and a sweaty headwall climb.

Ankle zips with an expansion gusset. Winter boots are bulky, and a trouser hem that will not pass over them is a daily irritation. The zips open the lower leg to fit over mountaineering boots, then close down clean. Combined with three leg lengths, you can get the hem sitting properly on the boot, which matters more in winter because a hem that rides up exposes the exact gap that lets wind and spindrift in.

Matrix RX reinforcement at the knees and kicker patch. Rock, scree and the occasional careless crampon swipe all land on the knees and inner ankle. The reinforced panels put tougher fabric exactly there without stiffening the whole trouser.

Add articulated knees, a gusseted crotch, a part-elasticated waistband with belt loops and two zipped hand pockets, and the feature set is complete. Storage is the one modest area: two pockets is lean, and anything beyond phone and snacks goes in the pack.

Fit and sizing

The fit is regular, which is the right call for a winter trouser: room to move and room to layer leggings underneath, without excess fabric flapping in wind. Sizing runs from XS to 3XL with waists from 71 to 101.5cm, and the three leg lengths (76, 81 and 86cm) mean you can buy the length rather than compromising on it. If you plan to layer underneath on the coldest days and sit between sizes, go up.

Torque VR vs Salomon Wayfarer Warm

The Salomon Wayfarer Warm is the other lined trouser we rate, and at around £110 it is the sensible question to ask before spending £165.

The Salomon is a hiking trouser adapted for winter: the standard Wayfarer platform with a brushed-back four-way stretch fabric, 385g, DWR treated, with knee articulation and the same three leg lengths. It is lighter, cheaper, cleaner looking and the better everyday winter trouser. For cold Dorset and South Downs days that end at a pub, it is the one to buy.

The Rab justifies its extra £55 the moment the ground gets serious. Salomon lists none of the Rab's mountain hardware on the Wayfarer Warm: no thigh vents, no ankle zips, no reinforced knees, and a simple brushed back rather than a zoned lining. On a mountain route where you climb hard, scramble, and then stand in freezing wind, every one of those gaps shows. Match the trouser to the day: Salomon for winter walking, Rab for winter mountains.

Torque VR vs Mammut Courmayeur SO

The Mammut Courmayeur SO (~£170) attacks winter from the opposite direction: no lining at all, just a dense double-weave recycled nylon softshell at 460g that blocks wind and relies on your own output for warmth, with ripstop reinforcement at the knees and lower leg and an asymmetric zipped hem with a boot hook.

For cold, windy, hard-moving technical days it is superb, and it never overwhelms you with heat. But for most UK winter walkers the Rab is the more forgiving tool, because the lining covers the moments the Mammut punishes: summit stops, lunch halts, slow scrambly sections where output drops and the cold arrives fast. Pick the Mammut if you run hot and move continuously. Pick the Rab if your winter days mix effort levels, which most do.

Pros and cons

• Vapour-Rise zoned lining adds warmth without the damp-then-frozen cycle a fleece lining causes
• Zipped thigh vents dump heat fast on hard climbs
• Ankle zips with expansion gusset fit cleanly over winter and mountaineering boots
• Matrix RX reinforcement at knees and kicker patch where winter terrain does its damage
• Fluorocarbon-free DWR sheds drizzle, dew and dry snow
• Three leg lengths and XS to 3XL sizing make a proper fit achievable
• Articulated knees and gusseted crotch keep movement free on steep ground

• £165 is a serious outlay if your winter is low-level walking rather than mountains
• Only two pockets, so storage beyond phone and snacks lives in the pack
• At 473g it is a dedicated winter trouser, too warm for most three-season use
• Not waterproof: sustained winter rain still needs an overtrouser on top

Verdict

The Rab Torque Vapour-Rise is the winter mountain trouser done properly: a wind-killing stretch outer, a lining that manages heat intelligently instead of just trapping it, and the vents, ankle zips and reinforcement that winter ground actually demands. It is the strongest option in its category on the UK market, and it is the pair I chose when the destination was a Nordic winter rather than a Dorset one.

Buy it if your winter includes real hills in real conditions. If it does not, save £55 and buy the Salomon Wayfarer Warm, or spend £33 on a budget fleece-lined pair for the dog walk. The full field is in the winter hiking trousers guide.
