Like most Smartwool products I have purchased, this one is a nice weight, completely soft and comfortable AND attractive. I get compliments on it all the time.
Bought this recently to have a second set of base layers for skiing. I have previously bought this product and it’s impressed me to the point that i now have two! Very warm while still being breathable and moisture wicking - perfect for skiing or hiking in cold weather to ensure you stay warm and dry. Highly recommend putting it through a wash cycle before wearing it for the first time as it will be rather itchy if you don’t (as i found out the hard way on the mountain)
Super comfortable first wear while on a 2 day backpacking trip. It made a great base layer and then when temps when up it was nice on its own. And a layer of sun protection with long sleeves! Odor control was evident, but control being the key word--definitely not absent. I recommend this shirt and look forward to using again on the next hike and for my trip to the Tetons next month (as well as trying as a base layer for snow skiing!).
Bought as gift for husband. Looks and fits great. He is short and very slim but the shirt does not look oversized. We ordered small. Color is gorgeous and true to the screen display.
Great, but not as soft as their warmer 100% wool, or the ultra lightweight but decent mid weight.Little scratchy. Don’t like the pattern but I got it on clearance 60% off, so worth it.
I have many articles from this company and they never disappoint. I bought a larger size so I can wear it like a shirt. Feel just as good as the others I have.
Love this shirt! I hate wearing synthetic material and this feels great and does a GREAT job as a base layer Also looks decent just to wear around
I’ve only worn it once, but it is just the right level of warmth hardly noticeable because it’s so thin so it’s very comfortable against the skin
XL size, fits well against my body as I had hoped, yet thin enough for warmth and able to add layers without bulking up.
My new favorite wool layer. It has been incredibly cold so I'm using it almost al the time. I also like the tied dye.
