Bought this for my dad to go hunting in, he loves them and says they kept him toasty warm all season. Warning - smells strongly of plastic/chemicals for the first few days after opening, so if you purchase as a gift, give them some time to "air out" if you can. This was not a downside for my dad as he specifically requested this kind of underarmor as a gift. The smell is just residual from manufacturing.
I got several of these for my brother when he worked in the Ukraine for two years in rough conditions, and in every picture I can see him wearing one under his shirt! He loved them and still has them three years later -- they are tough & the best for cold weather living!
I have used these for playing hockey and riding a motorcycle in cold weather - Misplaced or son may have thought he needed it more, in any case bought another - works great would recommend it especially for those cold rides.
