Customer Reviews Smartwool Merino 250 Base Layer Crew

A FB travel group recommended merino wool for travel because it packs well and can be worn multiple times. I purchased three brands and the Smartwool tops fit best, great weight. They were used on a 10-day land and train trip, no wrinkles, no odor. I plan to purchase more.

Love it for warmth and a pretty layer

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.

Plan to wear backpacking in the mountains.

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.

The garment was thinner than I'd expected but helped in keeping me warm while diving in Iceland. I was wearing another thermal layer on top of the wool, but the thin layer ended up being very useful for maneuverability and was fast drying when I got slightly damp.

Love this shirt! It was my favorite piece of clothing during 8 months of traveling. It can be layered over or under. Its comfy and I love the color (dark teal-ish). It can be dressed up or down. Can't recommend it enough!

I love to wear this under a vest - Sized up because I didn't want anything too tight

The only shirts I wear for cold weather runs. Alone or as a base layer.

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.

I purchased this shirt in Massachusetts on our Appalachian Trail thru-hike in 2023. I wore it everyday until we summited Kathadin. It kept its nice color, and most of all in spite of many washings and rough terrain, it has no holes. I had 2 merino wool shirts from icebreaker and they had holes after 2-3 wears, and those were worn for regular days. I am planning to wear this to our next thru-hike but probably going to get a different color too. Very impressed with this shirt!

I bought this for the look and fell in love with the feel.

These base layers are well-made and the fabric isn't cheap. I've been wearing them for years. I live at 7600 and it's cold here for most of the year. the colors are really pretty too.

This top is amazing. Not only is it soft and warm, seeing me happy in cool weather, but it is also very chic and I can wear it as a fashionable top to work. I feel terrific wearing this shirt and now own two of the exact same since too good to be true!

I have had the same smartwool layer for years and finally replaced them with a new set. They are consistently comfortable, smooth, they don't bunch, they're thin but so warm and so smooth on your skin.

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.

I use these for skiing and running in winter. I live the marmalade color. #sweepstakes

Best thermals! Not itchy, comfortable to wear on any hike or just relaxing.

I love these base layers, I wear them everyday in the winter under my sweaters and I also use them for running when it's cold.

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!!!

I live in these and have several I've collected over the years. They are easy to care for and still look amazing, showing no wear after several seasons. They are so cozy & warm that I get a little sad when it gets too warm to wear them. I am hopelessly addicted to Smartwool clothing.

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

Wear alone or as a warm, non-bulky layer when it's cold.

I purchased this in 2 colors, in 2 different sizes. I'm a size small on the size chart, but was torn between ordering small or medium knowing it would be form-fitting. I got one in S and another in a M because that pattern was sold out in S. And I can say they both fit generally the same on me. I would go for S next time, especially for use as a baselayer, but honestly the fit and look is pretty similar between both. My new favorite shirts!

Love this! I wear it all winter for cooler hikes and trail runs. Works well with a light layer and keeps me warm without sweating.
