It is a very comfortable fabric, and so far durable over the first 3 months. It keeps warmth well, and does a great job of not developing an odor. I use it to work out in the morning, and while I don't get real sweaty, I can easily use it over a month before I even consider washing it. The one downside is the size. I'm 6'1", 190 lbs with long arms. I got a large, and the sleeve length is adequate, but is very short on the torso. Other than that, would recommend.
[This review was collected as part of a promotion.] I wear Icebreaker boxer briefs everyday so I was really hopeful this would be the last set of long thermals I'd ever have to buy. Unfortunately I found the fabric to be too scratchy and uncomfortable on my skin. They look like quality pieces, just not for me.
[This review was collected as part of a promotion.] Did not expect Merino to feel so soft and light. Kept warm but not too warm on a coldish weather run (-1' Celsius). The only downside of these clothes is the drying-time (cannot tumble dry) so will experiment with wearing twice before washing.
[This review was collected as part of a promotion.] 200 weight is perfect for a winter base garment! It fits true to size with the sleeves a bit long, which I like. The neck fit is not too tight and the body length stays tucked in, even during repeated moves from standing to crouch.
[This review was collected as part of a promotion.] It's very comfortable. It can be used for three seasons by adding a layer inside or Outside depends on the temperature... Except Summer, I wear it a all year round
[This review was collected as part of a promotion.] This is such a comfortable and great wardrobe staple, perfect for layering under a jacket or hoodie. Great fit and very attractive.
[This review was collected as part of a promotion.] I originally bought this as a layering piece, but I now find myself wearing this in a non-sport situation.
[This review was collected as part of a promotion.] Bought for an active 70yr.old who rarely buys clothes. If he cares for the top, it'll last years.
[This review was collected as part of a promotion.] The quality is great and the shirt is very comfortable.
