I bought this baselayer to use for my recent snowboarding trip. The weather was windy and 8 degrees each day. I already owned the baselayer pants which were military issued. This top was perfect. It kept me warm for 3 days. All I used was the baselayer and a hoodie with my ski shell over the top. Perfect setup all day long.

I have used ColdPruf gear for about 3 years. Living in the northeast it gets cold. These products can not be beat. I highly recommend them to everyone.

[ Bought the set for my girlfriend and she absolutely loves it. Fits great and would highly recommend.

I purchased this top( and the leggings together as a set). Altogether, it is one of the better base layer fits I ’ ve had the chance to try out in the elements. Overall the top is probably my favorite piece, not only because of the high quality materials used- but because of the sleeve length. As a tall/lanky girly, some genuine long sleeves are always greatly appreciated. The style is also a great plus, the outfit goes with pretty well everything( purchased in black for this reason). The outfit looks great together, but they can also be interchanged with other pieces and they still look awesome all while keeping you warm:)

I bought the fay mid weight base layer top and bottoms and they ’ re perfect. They ’ re so flattering and cute on their own and keep me so warm

Fit is perfect, it ’s super comfortable- no tugging or readjusting needed throughout the day. Warm without overheating. And it goes so well with my navy ski gear from Halfdays. I always get compliments on the slopes!

I wear this for outdoor exercise, as an everyday mockneck, and even as a pajama top. Well performing and well constructed. Love the color too.
