Customer Reviews Smartwool Merino 250 Base Layer Crew

Keeps me warm on cold days.

This is a great travel shirt, breathes well, and looks nice no matter what

Feels like a nice sweater. Already ordered a short sleeve shirt and will be ordering more soon. Its a necessity in Wisconsin. My under armour is going out the door.

Used this on my most recent trip to alaska and I couldn't have been more comfortable. I used two of them for 10 days and they were comfortable, warm and dry every day. Also nice that they didn't smell so I felt refreshed every morning. Love all of my smartwool and this one is no different

I purchased this layering crew to take the place of another thin wool sweater that was worn out. I have to say this piece is super versatile. I can wear this with a tee underneath or on its own. It doesn't itch very soft and comfortable. I can wear this out or as a base layer. I liked it so much that I purchased 4 others. Buy one you won't be disappointed.

I bought this base layer for a hunting trip. I was looking a non-collar base layer. It feels and fits great. The Smartwool size chart was right on the money for my weight/body.

Picked this up last night as a random bd gift from my girlfriend. I am always cold so this seemed like a good choice. Wore it outside today (40 degrees) playing with the dogs. I only had a cotton tee and nylon pullover with it and *I was almost too warm!* After coming in and being quite warm from the temp change, I was never uncomfortable! This shirt feels better than cotton! I think I have found my favorite base layer... Can't say enough good things about this shirt!

I've tried many base-layers and this one is the best. The quality, fit, breathability, and versatility far exceed the performance of any others. I have use for this in temps ranging from subzero up to the high 50s (F). Not once have I felt sweaty or uncomfortable in any of these temperatures. You can really wear this for days and not stink up within an hour like the Patagonia capilenes and other synthetics. Without a doubt The 250s run longer and have a better fit than the 150s. Just don't forget to wash inside out in cool to cold water and hang dry for best/longest performance. PLEASE NOTE: this review is specific to the 250 layers.

This shirt has easily become my favorite! For someone who is wide in the shoulder area but not long in the torso the way the shoulder seems and length of the sleeves is amazing since i usually end up having to pick between too small in the shoulders or a dress in length. Only thing i want is a different color. If it was made in the same color as our military undershirts it would make a perfect layer for the cold days in the field especially for vehicle crewman who cannot wear most standard issue CW gear since it can melt in a fire.

This is the second one I bought, I absolutely love this shirt!

Really like the color selection (grey and black gets old), softness (not scratchy at all), and warmth of this shirt. Very much appreciate that Smartwool stayed with 100% wool too. Only complaint is that the arms are made for a human monkey. I'm 6'1", 195 lbs, 44 inch chest, and have above average length arms. Bought an L which has always fit me perfectly, and the arm length is down to my knuckles. Not a dealbreaker, but a weird cut compared to...literally any other piece of clothing I have worn.

This is my favorite sweater ever!

Got this b/c I needed to replace some very old LS shirts. It's amazingly comfortable and quite warm. Great as a layer around town during the transition season weather (50s-60s), especially nice for days when it is warm during the day but cools off in the evening since it packs down reasonably well. It's also subtle enough to wear just about anywhere. Haven't had it long enough to speak to durability and haven't taken it out on the trail yet

Just bought this as an undergarment for drysuit diving. Works like a charm; warm, soft, and breathable.

I wear this wool undershirt with my foul weather gear on a racing sailboat on off shore, long distances races where the weather can get very wet and very cold. This shirt, along with the long underwear, keeps me comfortable and cozy. Love it.

I bought this top and a bottom as a base layer for a recent trip to Iceland. It was the perfect base layer. I wore it nearly everyday, without washing and there was no stink - even slept in the bottoms. It was a little thinner than I expected so I brought along my fleece thermals as well, but I found I never needed them. This shirt was warm on cold days and breathed during the more strenuous hikes. My typical layering system was this as base, fleece for mid on really cold days, and 650 fill down puffer as outer. I found that for Iceland in March (temps around 30-32 degrees F during day) I just needed this and one other layer.

I bought this as a layering system for cycling and to try and minimize winter bulk. This base layer keeps me warm without overheating my body. Want to get one for around the house.

I love the pattern, the thickness and the softness of this top. It's great for layering to ski. Not too much nor too little.

This base layer can be worn by itself, or layered with a shirt. It's comfortable and warm; nearly perfect!

The warmth was great! Wore it on top of the smartwool short sleeve and a mid layer and then a ski jacket. Had no issues with -15 wind chill. The fit was perfect. I'm 6'1" and 140 lbs. The length is long enough to be packed into my ski pants without coming out during activity.

My husband is a large Tall Norwegian man. He needs it to fit his torso and long arms! They are great! As we just had 12 inches of snow and he is nice and warm, even while shoveling snow and ice!

I purchased three men's thermal base layer crews and the fit was perfect for all three. They use them for added warmth while skiing, snowboarding and snowshoeing.

Feels great and fits well

Size down for a form fit. Husband is 5'10" 190lb and bought a size M for a perfect base layer fit.

Great layer for cold weather running. Keeps me dry and warm.
