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

This baselayer top is awesome, is very warm, and comfortable to wear all day. It's long so it easily tucks in and stays that way. Or, if you don't tuck it in, the long waist hugs your hips and keeps the wind from blowing up into your open coat. This keeps you very warm, but is breathable enough to wear in the house all day. Wearing this in the house allows me to keep my heat much lower saving me $$$ on my utility bill. So while this is expensive, it has lasted and is great quality. I bought a 2nd one because I wear mine so often now I hate being without when I have to wash the one. Btw, I wear this over a cotton shirt, which allows me to wear it multiple days without needing to wash it more frequently. I think this too will make the life be extended. Definitely recommend. It's worth the cost. Also, the price on this in Oct 2021 was $20 cheaper than the 2nd one I bought in January. Not sure if that's a result of the inflation we're seeing now or because it's "in season" and naturally higher cost. I'm going to keep an eye on them and see if the cost drops in July when they are less likely to be selling.

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.

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.

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!

My husband loves this shirt.it keeps him warm all winter and fall!

I own about half a dozen of these shirts and they're easily some of my favorite wardrobe items. They're made from high quality merino wool that holds its shape doesn't pill-up after a few washes like some sweaters. The cut is fitted but not too tight, so it looks as good on a hike in the wilderness as in a smart-casual restaurant or bar. They're perfect for travel as they're light-weight and wrinkle-free. The material is breathable so it works equally well in warm or cold climates and is naturally odor resistant and quick drying. I highly recommend!

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

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.
