Customer Reviews Smartwool Merino 250 Base Layer Crew

A MINNESOTA staple ! I love these tops Warm, well made & a nice selection of colors. I'm 5ft - 100 lbs & wear a size XS. The fit is great Thank you Smartwool !

This top is comfortable and warm. It is not too heavy and fits comfortably under my tops. I am 5'7" and weigh 135 lbs and the medium fits perfectly. I have long arms and the sleeve length is perfect. This is a great product.

I use this product as an undergarment for running in cold weather. Love the comfort and the warmth it provides.

Love this top-not itchy, warm but not bulky. Can wear alone, layered and dressed up or down

It's my favorite most versatile item of clothing I own. I love to layer it in cold weather, or to create an outfit. It is warm, cozy and comfortable

I have used smart wool tops on my morning walks for decades. When the weather is cold, I layer up to two and when it's milder, just one. These tops are incredible. They wash up well and are worth the expenditure because they are durable. I have four smart wool tops. I highly recommend them.

Fit well and temperature regulating but I did find it itchy. Was hoping it would be more soft. I purchased a M which is the size I wear in most brands.

I layer this under my vest for Fall weather and love the warmth it provides! The patter is super fun as well. Winter time I use it as my base layer for outdoor sports and it keeps me warm and dry.

These are my go-to base layers for both touring and resort days. They're warm, with a good fit and they're not itchy. No complaints!

I volunteer for the National Park Service. I wear this under my uniform shirt. It is the perfect way to add warmth if needed and remain cool on those hotter days

Very pretty and well made leggings quality wise but very tight on me, I like compression leggings but these felt like they were squeezing the blood out of me and I’m small, only 5’2 and 115 lbs. I usually wear XS/S but the small where so tight I could barely put them on… very disappointed, I returned them.

Love the fabric & colors. Perfect for cold winter days when you don't want a lot of bulk or like to layer. Only reason for 4 starts is it runs a little small.

Fabulous warmth without weight! Wash beautifully. Perfect for skiing and hiking, but also lounging at home.

This is my go to under garment for cold weather. It keeps me toasty even on those really cold days. Smart wool makes the best wool products I have ever purchased.

I am traveling by train and found the weight/warmth to be perfect. It packs well, wears well for multiple days and it look great.

wow - do I LOVE this shirt! It's the perfect warm layer that can be worn alone or under another layer. I will be purchasing multiples! I bought an XL for some looseness - the "appropriate" size would have been skin tight.

I've been wearing these for years and years. The recent redesign is stellar - SO glad the arms became longer! Thank you for this change! The new side-seam design is very flattering. I live in these shirts - they are my daily morale boost. But please PLEASE bring back the Pewter Blue color! And also make Pewter Blue in the all-season weight... that is the best blue I've seen offered here the entire time I've worn Smartwool. And more classic rich alpine and royal blues as well :) It's nice to have options between super-light and super-dark and super-bright.

Beautiful, soft and quality base layer. The pattern is pretty to wear out and about also. I love this crew. It fits perfectly. I got XL because I want to wear this out and also hiking. It has nice sleeve length and shirt length and it's flattering.

Love these Smartwool crew tops and I own a little collection of them in various colors. Have noticed some colors are softer than others. They loosen up a little after some wears. Fit is athletic fit. I'm a size 10 and can wear a medium or a large. Or both for layering!!!

My go to winter top. Purchased in many colors and patterns. Feels great in colder weather and works with layers and vests.

SMARTWOOL is THE ONLY base I use for layering when hiking, traveling or even everyday. They are by far our favorite go to's. I only wish the precious blue was back. This is harder to match up to my other layers, but I love the fit and style.

I love these shirts! I bought a few or them for a trip and have been wearing them all the time at home! They are comfortable and keep the temperature comfortable

Love these shirts. I usually only buy one every 4 years b/c they last so long and wear so well.

I was worried when I purchased this amazing top. I'm 75 years old, small boned, 5'1" 105 lbs. and was concerned that it would not be appropriate for someone my age. Not at all it fits perfectly and I will buy more.
