Customer Reviews Smartwool Merino 250 Base Layer Crew

I use these under layers for skiing. Perfect fit and they keep me comfortably warm.

Used it couple of times only but feels really comfortable.

It fits snug, but that is what it is supposed to do. I use it as a base layer when riding or hiking in colder weather. Love the feel of it.

Bought it for my hubby for Christmas. Hasn't worn it yet, but the design and fabric are great. He will be nice and toasty!

I love the fact that Smartwool products can be washed normally ( we wash most laundry in cold) and then air dry. Fit is spot on. Looking forward to staying warm during the cooler weather.

Great as a base layer or by itself.

This SmartWool product is really nice looking and functionally it is warm, fits great and is totally comfortable. Love it so much I just asked to have another one!

Great looking base layer. Fits well even with a sport coat.

Good shirt. Ended up with a snag resulting in a hole about a year in. Smartwool replaced the item with a new, hole-free version. would recommend

I like it a lot. I usually wear medium tall but you don't offer that size. I risked buying a medium and it fits perfectly. The only improvement would be to have it be made of American wool and manufactured in America by Americans. Thank you my fellow Americans.

Excellent base layer under waders for cold weather fly fishing.

Beautiful neutral cream color that will keep you warm and go with virtually every outfit you put together.

Warm base layer! Perfect for cold days outside. I have several of these! Very durable

Base layer for fishing, hunting, football games etc.

A great base layer for skiing or a casual lightweight sweater.

Love to layer underneath a sweater for maximum warmth!

Perfect to wear as a shirt or as a layer. Even if it gets wet from water or sweat it still feels comfortable and warm.

This is a great layering piece and is great on it's own. My husband owns it in several colors.

Went on a ride with my E-bike and was amazed how warm I was when the temperature was in the 30's and cloudy.

I work outdoors frequently and have been looking for a base layer that actually keeps me warm. Smartwool products excel at this whereas I found synthetic base layers lacking in the warmth department.

This shirt saved my last trip to New York! The base layer is stylish enough that can be used as the main shirt and it protects you really well from the elements! It's also great to use while inside an airplane. Not too hot, not cold at all just right!

For light hiking these are supremely versatile. Perfect for the Shikoku pilgrimage. Two shirts, one pair tights, one beenie, three pairs socks- all merino wool. Combined with water and windproof layers I was comfortable in late winter/early spring conditions, 40 to 65 degrees for the seven weeks I walked with a 30L backpack. I am thoroughly pleased with the performance, styling and construction of Smartwool garments.

I recently went on a backpacking trip in freezing temperatures while in the snow I used this clothing for my under layer and it kept me nice and toasty throughout the trip. I would definitely wear this again.

Nice warm underlayer. But also looks nice enough to wear as a surface layer.

I have worn these almost year-round for many years. They are the best!!
