No, I do not recommend this product

[This review was collected as part of a promotion.] I ordered a long shirt to match this, and the shirt was perfect. The sleeves were extra long and the turtle night coming to cover. The face was perfect. But these are interesting because they are fairly short. I found it odd the sleeves on the shirt would be extra long but the pants were almost extra short. At least 4-5" from my ankles. They are comfortable and I wanted to like them, but they need to make them longer.

Icebreaker is hands-down the best underwear / base-layer brand in my opinion. These base-layers keep me toasty for long days on Ski Patrol, but also wick moisture and dump heat when I'm ski-touring. The durability isn't as good as cotton or polyester, but it literally never smells, it dries super fast, and it prevents chafing and sweating. Order at least a full size up if you're not used to a "European" fit.
