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 am getting synthetic products out of my wardrobe and I have become addicted to Icebreaker long sleeve layering shirts. They are extremely comfortable, come in a variety of nice colors and weights, so are quickly replaced my synthetic top layers.

[ This is one of two or three of the most amazing clothes I have. Technically it's a base layer but it's something I wear almost anywhere with the right pants and shoes. It's wool, but it's incredibly soft and comfortable. It works great as a base layer, but it's versatile.

[ I was looking for wool thermal layer for my husband, who runs cold. Rather than settling on a bland look, I chose this colorblock version for its added style. While he does n't fill it out quite as nicely as the model(!), he looks great in it.

You don ’ t realize how much you need a heated base layer until you have one! It ’s been such a benefit to various aspects of my life. I wear it beneath my layers when spending time outdoors during winter in Wisconsin. But I ’ ve also worn it to work( in an office) during especially cold days. It fits true to size and is comfy. Somehow it seems to trap heat inside yet it ’s also breathable, I don ’ t sweat in it like I have with other base layers.

The Base Layer Shirt takes the bite out of any cold day! And the battery last for hours! Washed it in a cold wash then hung it to dry, easy peesey! Definitely worth it!

I bought the base layer for my son who works at Disneyland in Anaheim Ca. and he loves it. Keeps hos 3X body warm when working nights. Great product

Just wearing the shirt and not on has been enough to keep me warm. The few times I have used the heat, I set it on lthe lowest setting and was plenty warm.

Definitely worth having extra battery banks if you ’ re skiing all day or anything like that, also could use an extra hole in the battery pouch so you can route the cable to a pant pocket more easily. Besides that, it definitely lasts through the wash and multiple winters

[ This base layer is really comfortable. It is warm and does not restrict movement. I wish I had found this earlier. Fit is true to size. I 'm not sure why anyone would not be happy with this- buy it!

[ Merino is THE stuff for active comfort in the cold. The key is staying dry between rain, snow, and sweat... it's challenging. 100%( 95 and 88 also good) merino helps to achieve this goal. It's warm when you need it to be and water( all types) evaporates quickly to keep you from getting chilled from damp clothing. It's got to be part of a system though, and you have to use that system properly or you will get damp and cold. We just came back from five nights in our tent@ an avg. of 26F at night. After hiking all day in these and then, putting on fresh Smartwool tops and bottoms we were warm all night( we could have stayed in the same set if we had to). Medium weight is probably fine for most applications, but do be sure you 've got the right system for the conditions. In summer and spring it's less critical, but in winter( THE best time IMO)... having the wrong gear can make for a miserable experience... and a dangerous one. Smartwool has the added benefit of being able to go in the dryer at home... not all merino products can. That's my take.

[ When it comes to staying warm during the winter, base layers are KEY! My old Smartwool long- sleeve lasted me years of use. Loved my first one so much that when it came to finally replace it, it was a no brainer. Kept me comfortable and warm during winter months of New Zealand, Japan, all the way to the summit of Mauna Kea. I 've never had a base layer fit so good right off the shelf. Felt like it I was putting on my favorite tshit. Could n't recommend it more
