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.

Mike B.
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!).

Perfect base layer for Spring in the mountains. Not too light, not too heavy, just right.

[ I have purchased a half dozen Carhartt Base Force crew shirts. Yes, they 're expensive. Yes, they 're worth it. They keep me extraordinarily warm, and they 're very comfortable. They 're worth every penny you 'll spend. Buy one for your dad, too. He 'll appreciate it!

[ Best value for your money as far as base layers go. You can spend 3x more on Smartwool or Icebreaker if you are looking for the best with a hefty price tag. Overall, this lives up to Carhartt ’s name
5
Bobby
[ I knew I was getting a good shirt because this is my second one. It fits snug enough to keep out the wind. It wicks and dries like an athletic shirt. Since it is 100% polyester, it is likely more durable than most. It keeps its shape and looks better than most.

[ Carthatt is a quality brand that is made affordable. I used this for my snow trip and it gave me warmth so I do n't have to layer too much. Very satisfied with my purchase!

Jag26
Like the feel of this LS tee. Can use it as a base layer or by itself on cooler days. I personally used it for an outdoor run and felt great. One thing though… while the fabric is intended to wick sweat out, I did notice the tee being soaked so not sure I ’ ll be taking it out for runs again. The length of the tee is also a little short so consider that if interested in this shirt.

I do n't review products often but I have had lots of Smartwool stuff and always been impressed so her goes: So far this garment is awsome. The wieght allows it to be worn as a primary layer or under a shell. Medium fits me perfectly at 70 '' and 170 lbs with a light liner underneath. The hood fits tight when in use, maybe too tight, we 'll see. after I break it in. It also covers the chin and mouth area when pulled up. It could use a chest pocket. I will be using it during a golf trip toi N Ireland with temps in the 50's and 60' with wind and rain; part of. a layering system I 'm bringing.

[ This has become my new favorite baselayer. It ’s form fitting and the multi panels really make it articulate with my movements. I wear it as my only layer in damp mid thirty degree runs. Also looks good to wear on its own out and about.

[ This is a quality built base layer and I 've worn it by itself or under a light jacket for plenty of warmth. Be advised to go one size up, especially if you have an athletic muscular build. Fits close to skin, athletic cut for sure. Looks awesome.

[ I was worried about it being too long like some other smart wool tops I ’ ve bought but didn ’ t have any problems. I ’ ve hiked with it twice so far and didn ’ t need anything else until it got below freezing.

Absolutely love the lightweight fit and comfortability. It fits true to size. This is my fourth purchase of this line. Each has been exactly the same in fit and comfort. And amazingly the fabric keeps your body temperature warm yet it allows it to breathe with changing temps to create a perfect balance of core temperature.

Jeff D.
I live in the northeast part of the country and the climate is cold in the winter. I love my Smartwool base layers. I have had earlier versions of this base layer and I was able to get a newer version on sale( lucky me!!!). I tried it on and the material is super soft and comfortable.
5
Joseph M.
This is the best mid weight zip neck base layer I ’ ve ever owned. The quality of the fabric is unmatched. I ’ ve never had a Smartwool garment that pilled. It looks good enough to wear as a shirt/sweater. The zipper is first class and the neck doesn ’ t sag. I were it as a base layer skiing all over the IS and Canada, cycling in cold weather, and under a shirt all winter to take the North Atlantic chill of fall through spring. Best of all I can wear it without worrying about the dreaded polyester stink, its stays fresh for ages.
$159.99
I highly recommend the heated base layer for anyone that spends time outdoors in the winter. ... It ’s just the right amount of heat in the right places to make cold winter hunting trips much more

I started with the Action Heat socks, and had to add the base layer to my collection. It ’s just the right amount of heat in the right places to make cold winter hunting trips much more enjoyable. I highly recommend the heated base layer for anyone that spends time outdoors in the winter.

Motorcycle C.
I got this primarily for motorcycling in colder weather. It works great. I can wear this with my jacket and jacket liner and I do n't have to wear other layers. I 've only used it so far riding in 50 degree weather but it was warm enough I had to turn it down or off. I usually wear a large but wanted it to fit tighter so I got a medium. The medium fits great. I would say the medium fits me perfect where normally I would wear a large t- shirt or long sleeve. Not too tight but not loose. Have n't had long enough to know how long the battery would last but have used it for a couple hours switching between high and medium and still have battery left. Would definitely use while skiing, etc
