Okay
Very comfortable to wear, dries quickly and wicks away perspiration very well. Don't hesitate to buy a tight one because the fabric relaxes a little after the first few wearings/washes. Ideal for mid-season and summer at altitude (a bit tight for ski touring in the middle of winter (well, what's left of winter...)
I recommend it for all your sports activities or if you are unsure whether you will be warm enough in short sleeves or too warm in fleece! Tested as a first layer for downhill skiing and hiking with a thin polartech fleece and a goretex! Perfect in temperatures from -10 to +5. Also tested for winter climbing in the calanques, it's perfect
Top and very comfortable
Maintains body heat, quick drying
I didn't expect any miracles from it, I even forgot I bought it. Then I found it in the closet and took it with me on a two-week trip and I have to say that it's amazing. In fact, when I wasn't working, I wore it day and night in the hotel for two weeks straight. It's fantastically comfortable, lightweight, lasts at an even temperature and almost never has an unpleasant odor, even after two weeks of continuous use! It's like my second skin.
It passed the test on a ski tour on the first day after purchase. It wicks moisture away well and dries quickly
Perfect
It works great as a first layer. It stings a little at first, but it's a minor thing because it's wonderfully warm and you don't smell after being active in it. And that's the main thing for me.
Perfect! Warm and dries in no time
T-shirt used for skiing for a week or two during the year, comfortable, but it gets in the way a lot, compared to other products from other companies the product is poor
I've already tested it several times in a very short time. Very comfortable to wear, very warm, doesn't itch at all and dries very quickly.
Very good product, keeps you warm in these weathers, and dries quite quickly after washing.
Very comfortable, close-fitting cut. Very pleasant to wear, quick wicking of perspiration.
a t-shirt that shows its qualities well if you use it regularly at the beginning I didn't find it that good, I didn't find it that warm and the start of winter arrived and since then in d+ and descent it keeps me warm but not too much, at the bivouac it's great!!!
