Scottish Winter Mountaineering - V.COMFORTABLE

Bought these for a Introduction to Mountaineering weekend in Aviemore. Day 1: great weather, worn with 3/4 Skins compression shorts underneath and long ski socks. Day 2: Minus 8 Centigrade, 50mph winds last 4 hours. Worn with ordinary undershorts. Bum was a bit numb standing still with back to wind but moving no problem. These thing are VERY WIND RESISTANT and HIGHLY BREATHABLE. VERY COMFORTABLE with nicely fitted high back. Obviously in such conditions I should have had thin tights underneath or an over-trouser but they performed admirably. Truly great piece of kit punch well above their weight both in price and grams. Also perfect for more miserable dog walks. Some minor damage on outside of cuff (outside reinforced area). Not sure what caused it but tough material that resists dog claws so... GET SOME!


Definitely recommend these pants

Great ski touring pants at a great price

Bought these is Decathlon in France and wore them for two weeks with over 5000m of touring. Rugged and comfortable. No damage from skis or crampons. Recommended

Great trousers for winter walking

Grabbed these in the sale so an even better buy. Bought ahead of a planned walking expedition in the Lake District during late December. They were extremely comfortable - the braces helped - and kept me perfectly.warm and dry throughout 5+ hours extreme walks.

Robust Heavyweight Garment

Used these on a multi-day trek through the Cairngorms with some grim weather. Worked really well in the wet and cold. Teamed them with Kalenji running shorts, just as well during the heat of the day a bit too heavy even with the vents open. just the thing for the cold evenings and mornings. Loved the internal gaiters, worked really well on multiple stream crossings.

perfect for cold weather exercise

bought these for cross country skiing in Norway ... -15 degrees c here. Kept me warm, ease of movement when skiing/snowshoeing, ventilation panels nice for when get too hot. Like them a lot!

Overally good but bad breathability

I bought these pants for colder autumn hikes and winter skitouring. I find the pants very durable, with good shape even though the knee part is below my knee, enough water repellence and reasonable price. The only very bad thing is breathability. I usually wear my merino underwear during the skitouring, but my tights and ass are always totally sweaty. I always open ventilation zips, pocket zips and even middle zipper, but it just does not breathe.

Great but a couple of flaws

The colour of the pants is not the best for sunny days on snow, as they end up feeling like an oven due to the black colour absorbing all the heat and then will feel cold when in the shade. A grey colour would be a more suitable alternative. The second flaw is the built-in gaiter which doesn't stay on the back of the boot. An elastic band (or similar) to put under the sole of the boot would be useful to keep it in place. Apart from that they're great, both for mountaineering and ski touring.

Excellent product

I bought these to wear skiing on the haute route and for general alpine use and found them to be an excellent product and on par with trousers at twice the price. Genuinely, the quality is very good, worn for at least 20 days with no signs of wear. The fit is very good, i wear a large (32" waist 5'10"). Yes i could have bought trousers using slightly better materials but this would have cost 3-4 times the price and for approx 14 days use a year i feel it is not worth the extra cost. I would never have questioned a price of say £120-150 if these trousers were sporting a different brand, these are that good.

Good product - but ..

Pleased with the quality of these pants and the various features. All for a really good price. However the size confuses greatly. They are definitely on the small side of the waist measurement stated. I am undecided as to return or not as a larger size will be way too long. Does this issue arise with other products? Recommended with caution.
