Another nice piece for layering in the winter, I hate shirts that have a wide loose neck but this is very nice stays up well . Fits nice and snug you don't want a loose 1st layer if top is loose the heat will escape . Happy with purchase nice quality

Keeps me nice and dry. It's not stinking like my under amour did, so thats awesome!!. It's a soft comfy shirt, most importantly... it feels good on your skin, made with quality material to last, great first layer, i got a medium, im 5'10, chest 40, waist 32. perfect fit :) I buy 10 of everything if i like em,,, so if they dont have black medium left it's cause of me. ha ha sucka!!!

Wore it for three days straight on the most recent trip, with a fleece and a gore tex jacket in 0F weather. Did it's job very well.

I just took 2 of these baselayers on a 10 day trip through the San Juan Mtns, Arches, and Yellowstone. They may appear thin, but they provide a very large amount of warmth. I layered these under a 100 weight fleece and was fine in the 40's. They are definately worth purchasing (much cheaper than Under Armor). This site also provided its impeccable shipping speed.

I interchange this with my cold gear and these are awesome crews! They keep you dry, comfortable, cool/warm (depending on how you dress) in most hiking conditions. Will add more to my collection. Good prices too. Way to go backcountry!

Dude, this Lightweight Crew is a quintessential piece of Marmot gear: light, durable, comfortable, super functional, and stylish.

I've worn it running, biking, doing yoga, even out to jazz clubs and more formal classical music concerts. Seriously, underwear or dress up, it's totally happening,

Go for it!

I took this on a long climb and it worked beautifully. Definitely got the sweat off my skin so I wouldn't freeze in 15 degree weather!

I wear these for my base layers whether I'm working or playing. I spend six months in some of the harshest conditions in Afghanistan and th other six back home in Alaska. My gear only gets one chance for repeat use and this Marmot performed so well I bought more. They provide the 'comfort' level of warmth without generating overheating conditions. The fit, finish, and feel are second to none.

Great fabric. Had to return due to size running one size smaller.

this is pretty awesome. very comfy and warm and i look pretty good in it. not much else i can say except it fits well and has no flaws, which is a pretty big deal in and of itself. this and the marmot lightweight bottom i picked up have made me a marmot brand whore.

Got this as a replacement for a midweight crew I have been wearing for years. Totally impressed with the weight, fit and overall comfort during our first few weeks of cold temps in Utah. Can't wait to rock it as my base riding this season. A little loose in the collar, but you Ute linebackers are gonna be warm when you stomp on them fancy Cougars from Happy Valley!!

This is a great base layer for freezing conditions where you know will be working hard on the hill. I sweat and this thing does not stink because it wicks the sweat off and the cocona technology actually smells like coconut amazingly.

Wicking power combined with serious comfort - can't beat it!!!

This was amazing gear I got wet over the weekend and it dried out fast and kept me warm. It was nice.

These fit great they are not as fitted as the Under armor ones I have wide shoulders and the XXL fit well. No pinching under the arm. I'm a 50 inch jacket and 36 inch waist. Dried fast. Wore only this up to Camp Muir. in about 40 degree weather.

The fabric was super itchy. The quality and fit were good, but I would not recommend based on overall comfort.
