Lightweight layer if the days warms up, but warm enough to stay warm if the conditions are between temperatures.

[ For reference, I purchased a Medium. I ’ m 5 ’ 4 ”, 128 pounds, pear shaped, so, smaller on top, curvier on bottom. I got the black which is opaque. I wear this baselayer weight for cross country skiing when it ’s above 30 degrees or so. Smartwool varies in size for me, these are not extremely fitted like some of the 1/4 zips so go with your normal size.

[ I love this shirt. I recently got another few to fill up my wardrobe after a move from AZ to OR. I have had the originals for almost 9 years and wear them all winter long. I have been hiking, backpacking, and traveling with them and they have withstood the test of time. They are comfortable alone or as under layer. I additionally regularly wear it as a mid layer with a smartwool tank below. I truly love these shirts. If it helps, I wear an XS and am 5 ’ 2 ’ ’ and 120- 130lbs depending on the year.

It's a great fit i will get another one but this time in medium size. It's a hit& miss on my end.

I purchased one of these and liked it so much I went back and got another one. The fit is perfect. But I did have to size up to an extra large which I have to do with all Carhartt space layers for their shirts. But I like the fit and I like the materials. I wear them at work and it's a lot better to sweat in these than it is a cotton shirt. I believe these are the newer models also as they do n't have the sewn on Carhartt tag. Nonetheless they are still quality shirts but are a little on the pricey side at$ 50 each. But still worth it in my opinion.

Little expensive for a base layer but it does its job keeping you warm. I used it a few times and it does work. I will say get one size up runs small. I am 6ft and 185 and my normal is L but had to get an XL.

This is great base layer! As far as the appearance parameter goes, I suppose that is limited by the user. But the shirt itself is great.

I work outside at our airport, mostly outside for hours at a time, sometimes in and out in and out. This piece surprised me. It ’s warm, breathes and I don ’ t get sweaty going from cold to warm. I ’ m 5 ’ 7 165 43 chest 33 waist. I went large and got a perfect fit. I ’ m usually between medium and large in Carhartt so, I have to gamble on everything I buy. This is a winner for me.

[ 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!

[ My old lady and I have the smart wool top and bottom 250 base layer set. They are exactly what you expect from smart wool. Great quality, the warmth I needed, and pretty useful in most conditions. If you need a base layer or something lightweight to wear on a chilly/cold night- These are useful and for great value.

[ At first these pants feel sort of itchy but once you 're moving around in them it's very comfortable. I first wore them in 35- 40F under normal hiking pants and was too warm while moving. They do regulate body temp well but I wo n't be wearing these hiking unless it's below 35F. I 'm also not a cold bodied person and I move fast.

[ We live in Minnesota, and have pretty cold winters. This baselayer has kept me much warmer than my old baselayers, so far! Great for running, walking or casual use. I plan on using them for a winter camping trip coming up as well.

Great wool baselayer- lighter than some of my heavier ones, which is exactly what I needed for touring. Does n't get too hot on the uphill compared to the heaver weight merino baselayers I have, still keeps my warm enough, easy to layer with, really enjoying it!

lizardblizzard
I bought this for my husband and its one of the most worn items in his closet. He has a really muscular build, so he is always looking for low- bulk layers and this is perfect. He likes that he can go directly from a zoom call( looks dressy enough on screen) to working outside( durable) to skiing( warmth under a ski jacket). He finds that he wears it most often as a mid- layer, but has worn it next to skin, as well. I am online buying him a few more in other colors right now!

I bought this Hoodie for a cold weather trip in the fall. Great fit& style. ove the black with gold contrast. It's a great base layer and will hardly takeup any carry- on room. Great produt from SmartWool!

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.

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.

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.
