Customer Reviews Smartwool Merino 250 Base Layer Crew

Last week in Wyoming , Thanksgiving week, active during the day was ok. At night I wore other layers. , including the base layer bottom.

Simply the best winter base layer I've found. Far superior to those "synthetic base layers" . I use this all Winter long when I'm skiing / snowshoeing / hiking / or just out for a brisk walk. #SmartwoolLove

This is very warm!! I run relatively hot so it's too warm as a baselayer, but I wear it as a mid layer for things here I'm not generating my own heat, like downhill skiing or if I'm going to be standing out in the cold for a long time. I do use it as a baselayer for cold nights when I'm camping. It's extremely soft and cozy, and very warm for its weight, so it's great to have around, and it was immediately an essential part of my wardrobe!

Love this stuff

Love the 250. Super warm and soft. Own many pieces. This is for my son. He now has a great wool base layer to hunt in.

This is my second SmartWool base layer, and I'm glad to have a heavier weight top for layering.

Will purchase again. I am a hunter and fisherman and I absolutely love these base layers. They keep me warm and comfortable. This is a ust have for my closet and cold weather.

Most comfortable base layer I've been able to find. Bought one and then two more as soon as I tried the first. Perfect first layer for late fall bike rides in Minnesota. Needed warmth but also very breathable.

Except to wash, of course. This base layer is super comfy and stylish. It keeps me warm and dry while I'm out and about during cold days. Also, Smartwool, feel free to send me some sweet free stuff as a thank you for this shiny review of a wonderful product :)

This product is worth the money...very comfortable and warm. Sizing is true to the chart.

Fits great, warm, good length.

Nice base layer, soft fabric! Purchased for my slender 6ft son - medium fit well, not too tight and not too loose, so he felt that it would work well and be comfortable to wear.

Wow, wool is crazy stuff. I was only a wool socks guy until I finally pulled the trigger on this wool baselayer and a lighter weight short sleeve option. This shirt is warm and the thickness of the fabric makes you think of fall, but I was impressed with the temperature regulation hiking out of our July overnighter spot, didn't really sweat or overheat at all. It also fits me really nicely. Props to smartwool for making their medium long enough to tuck in.

I purchased a medium so I could wear it over t-shirts...when I go hiking or any outdoor activity. I'm 5' 8" and weigh 145lbs...and I am fit.

I am 5'9", 152 lbs and I bought a small. The length of the sleeves and shirt are perfect for my build. This is intended to be a layer and the fit is slim. I am relatively thin and this shirt is fitted throughout. The material is great. It's very soft and a really warm base layer.

I bought one of these probably 10 yrs ago and wore the heck out of it. I often wear it as the top layer because it looks great. It held up great but it is now showing its age so I bought another. Saved 30 dollars on the olive and it's a fantastic color. Very dark for green. This product is worth every penny.

This is my second Smartwool Merino 250 because I love it. Super soft and comfortable for a base layer, I would love to have more of these.

Beautiful slimming base layer. Excellent quality..

I bought this garment hoping to add to my cold weather golf gear. After receiving it i immediately put this in the starting rotation. It is everything I am looking for in a base layer. Highly recommended.

I have just been wearing this as another long sleeve too but plan to use it as a base layer. 6'3, 185, athletic build and the large is perfect. Absolutely love this top.

Purchased for base layering - skiing and regular winter wear. Go-to base layering for my winter golf outings too. First time to purchase Smartwool - was absolutely surprised by the quality, fit and feel of the product. We are sold on Smartwool!

A great baselayer to add to your quiver. I also use it as a primary shirt around town sometimes, as well, since it looks nice on its own! It is an athletic fit, so if you want a loser fit, I would size up. I got the Large and it fits me perfectly (6'3" and 175lbs). Definitely recommend.

This is a fantastic shirt. Lightweight but still thick enough for warmth. Super soft

Fits very nice and like all Smartwool fabric it's so soft. Better quality.

I mainly wear this base layer while hiking, camping, or when I want the best balance between warmth, comfort, and breathability. It's amazing how it doesn't retain odor and how fast it dries. Most of all, it provides excellent warmth.
