Customer Reviews Smartwool Merino 250 Base Layer 1/4 Zip

I bought this as an early Christmas gift this year, and it was perfect. The receiver loves it!! Very soft and a great fit. It will be perfect for Illinois winter running under a vest.

So warm and comfortable, I layer it on top of my hoodie on cold morning hikes. I'm a satisfied customer!!

I have several of these and they are quite comfortable for skiing. They fit well and add a layer of warmth

Would definitely recommend !

I wear this top hundreds of days a year. It's one of my favorite tops!

Great for backpacking and bike packing. Doesn't hold odors and keeps its shape

I wear this every day in winter, either under other stuff or on its own, often with a t-shirt under. It's lightweight so if I get hot I take it off and put it in my bag, but if it's really cold I can easily wear another coat above it. It's really warm considering how thin it is, and, surprisingly for wool, it's very resistant in the Kai dry machine. Just got one for my 4 year old girl and she loves it!

2nd time buying one of these, love the weight-warmth ratio.

Use as a base/mid layer for skiing and winter camping

Purchased for my man for Christmas. I'm glad I did. It's so soft and the quality feels nice.

Worn at a cold football game. It did the trick.

This layer looks good and performs well. I wear it over a T or short sleeve button down for nights out and wear it as a base or second layer for cool/cold weather activities. Perfect for travel as it serves two purposes.

Second time I've bought this for my husband. He loves to wear with a sweater over or a tee underneath

Wonderful base layer that you can also wear as a lightweight sweater.

I buy one of these for my son in law every Christmas because he is an avid Boarder and rides nearly every day in the winter in CO even when the weather is below zero. But he wears his Smart Wool which not only keeps him warm but wicks away perspiration from riding so vigorously!

Used as base and/or mid layer. Fits perfectly. I am 39" Chest, 33" sleeve, and 15 1/2" neck.

Underwear for winter motorcycle riding and skiing. But it's so comfortable, I often just wear it around the house.

Comfortable patterned base layer with articulation during high outdoor activity or lounging around when you peel off your outer layers after a day in the outdoors.

Great comfortable base or second layer on chilly mornings. Love these! I must have about 8 by now!!

Excellent quality, would defeatedly recommend to a friend or family member! Looking forward to waring often.

Living in these- perfect for fall/ winter/ spring

Very comfortable layer. Warm without being too hot and bulky. I love it so much I plan to get it in another color. I am thin so it fits me just right.

Perfect base layer for cool mornings. The Medium size is a snug fit (5'7', 145lb athletic build), which is exactly what i wanted in a base layer. I ordered two more after trying the first.

This is my go-to for fall, winter and spring biking riding. Perfect weight alone or under a jacket as the seasons progress. The zipper allows a bit of air to get in when things warm up. Great fit, good length. Absolutely love it.

Works Great as a close fit base layer on cold mornings on the water. The zipper is nice for helping to vent later in the day when it warms up. The size M fits me pretty tight at 5'7" 145lbs. I wouldn't want anything smaller than a M.
