Smartwool Men's Classic Thermal Merino Wool Base Layer Crew (Slim Fit)

Light, but provides the right amount of cooling and warmth. I was initially skeptical due to the price, but this was a great winter essential that also wicked my sweat in warmer temps.

Looks good, feels good, wears well. Nice color. Can be worn several times between laundering. I own four shirts in different colors. Most brands are only available in black.

Switched from under armor to these. These run a little bigger and are about as thick as the 2.0. I wear 2xl in under armor and went with an 1xl on these. Fit great

Lifesaver during my snowmobiling trip to Yellowstone! Very comfortable, comfortable, but don’t let lightweight fabric for you, it really does its job well!Cheers!

A very durable soft wool fabric! Despite the fact that this fine wool garment was delivered partially outside of the very thin, unsealed, clear plastic sleeve it was shipped in, it held up admirably well. I expect it will give me years of good comfortable service, because using it as a hiking and climbing base layer next to my skin will subject it to less wear and tear than it experienced during the shipping process.

I am a veteran and these things are way better than what I was issued in Alaska (88-90) obviously cold weather clothing has made major improvements

Smartwool a very intelligent buy!

Love this company. The quality did not disappoint as always Made my trip to Iceland much more enjoyable knowing I could rely on the warmth.
