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.

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:)

Top is very soft. Not scratchy like some other brands. It ’s a great baselayer for colder days. Not sure how it will perform in freezing temps but did good around 40 degrees. Love the sleeves you can unfold and cover your hands.

This shirt is very soft. It is shiny material on the outside and fleece on the inside which makes it super warm for fall and winter. It is slim fitting so the shirt would paid well under a sweatshirt or vest or by itself.

Cori
I highly recommend this shirt! It is very warm and cozy. It is marketed as a cold weather running shirt but I use it as a base layer for outdoor activities. I have worn it under a hoodie while attending my son's Friday night football game. It kept me warm throughout the entire game. I also use it as a first layer when walking my dog in the cool mornings. The extended sleeves with thumb holes are a nice addition and really help to keep my hands warm. It washes nicely and stays true to form.

The shirt is comfortable to wear.

I bought this top a few weeks ago and so far I have worn it only once to ski in the East coast. I can not emphasize how warm and cosy these Halfdays inner layers! I never feel cold on the slopes even when I am not actively skiing. The color is also perfect and goes well with almost anything! I can ’ t wait for more colors to come out! FYI I am usually an XS but I bought the top in S because they ran out of XS for this specific color. I initially thought S would be too small for me( it looked small) but it turned out to be just a little bit bigger than the usual fitted look an XS would have. I think the top is definitely true to size so I would recommend getting your regular size.

Karley
I bought this set in pink for a ski trip to Aspen and it was amazing! The set kept me so warm on the mountain and the grip feature on the top prevented it from not rolling up. I found this outfit to be so flattering I even styled it with a fur coat to wear to apres and to walk around in aspen.

[ For me, a little snug in the stomach and chest, but still flattering and good fit overall. Gives a nice amount of warmth considering how light and thin it is. I like that the zipper opening goes down so low to help with overheating while hiking. Size M works well for me. 5' 4' 127 pounds.

Got this for my daughter, she is a teacher. Her room is cold and then she has bus duty periodically. So the 4. 0 is perfect for being somewhat sedentary. Surprisingly, actually keeps her warm! She is a chilly person normally, so cold temps are miserable for her. We 've tried many products. The Under Armour is work the investment!

Robin
[ My husband was so embarrassed I kept wearing my previous icebreaker from time to time, even though it become literally threadbare in a couple areas. Was nervous an updated version might not be as good, as often happens when one buys a replacement for something they 've loved so much, but so far this one has the same fit and feel as my beloved first icebreaker shirt. As well, they are usually `` updated '' colors offered and I was glad this one is pretty close to the original. I 'm sure I 'll get as many years wear out of this one as I did my first and recommend it strongly to anybody who likes winter sports or just comfortable shirts to hang out in during cooler seasons.
