I have been using the backcountry baselayer throughout last winter and found it extremely effective. It's definitely on the warmer side of my baselayer collection so good in cold weather, although in warmer conditions it does pretty well because of its breath-ability. I like the feel of it, it's comfortable to wear and the cut is nice. it's one of those tops that you can easily wear at the bar and not look like you're wearing a baselayer (sounds a bit weird that but i just mean it looks good off the slopes too). One of the most impressive things about it is its lack of smell. I have never had a baselayer top before that i can wear for more than two days. This one, i have worn it for at least ten days skiing and it still has absolutely no odour at all.I have also worn it during colder mornings during the summer and autumn when playing tennis - same thing, still haven't washed it but it looks clean and doesn't smell at all. I really should wash it, but I'm kind of seeing how long it will go before it smells.

Great fit, very comfortable and satisfyingly technical. Best designed technical base layer on the market by far.

Great product. excellent combination of warmth, sweat wicking, compression. Allowed me to ditch my warmth layer during spring conditions.

I've probably done 20 days of ski touring in mine now the full range of alpine conditions. Definitely the best fitting and most versatile base layer I've used. A better fit than the Icebreaker ones I usually use and seems to wick away sweat better too.

I love the brand and highly recommend it. It's great quality, super comfortable and gets a 10/10 from me.
