I needed some extra warmth through the recent polar vortex....... this was just the ticket for layering underneath my winter jacket. I received several compliments!

Got this for xmas, and ive been wearing it on every cold run and while skiing. The best part of the top is having the hole on the sleeve for your watch. My only complaint is that the pocket is too far to the side, but i can deal with it.

I have been buying the `` Varitherm Expedition '' long johns for decades. I became aware of them when my children were young, while comparing Dick's in store selection quality.

Will not likely wear before the fall season, but it seems perfect for skiing- light fabric for packing, but plenty of thermal warmth. The color was lovely too- subtle rose!![ for layering... sleeves were not super long, so not need to stuff under your jacket.] Would also come in handy alone for fall golf! Also a great name for teens- I got one for my 16 yo granddaughter as well.

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.

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

5 K Nicholson
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:)
