Customer Reviews Smartwool Classic All-Season Merino Base Layer Long Sleeve

Husband loves these shirts Cool enough to wear as sun protection while working, warm enough to be great base layer when cold

Walk or hike. Or everyday wear

This is the perfect weight for hiking, mountain biking and similar activities in climates where the weather can change quickly, particularly in the summer months.

This under layer and its older siblings in my drawer are daily winter war for me -and the blue is a fab color~!

Everyday use

This is shirt is great for layering when it's cold and great for outerwear when it's not

I love these baselayers for backpacking and everyday use. They just feel the best. Perfect for warm or cold

Fantastic shirt. Very light weight and thin but incredibly warm and breathable. Very comfy.

I bought the same shirt 15 years ago and have worn it for 15 years, I like it, and am pleased to have a second one

This is my favorite long sleeve T-shirt to wear during the winter months. I need to order more. Launder in a mesh laundry bag. Dry and delicate. Perfect every time.

I wear this base layer in the cold operating room under my scrubs. It has been a game changer for me! No longer am I shivering halfway through the morning. Even though the room temp are in the low 60s, I don't need to resort to the cumbersome jackets and fleeces that many staff members wear. I machine wash and lay flat to dry, and they dry quickly! I can't recommend these enough. Well done, Smartwool!

Great base layer! Keeps you warm in frigid temperatures, yet you don't sweat while doing work. Highly recommended.

Incredibly comfortable. I love to wear it around the house and also for hiking and backpacking

I wear it, it keeps me warm

I bought this base layer to help keep my man warm on the golf course, on hikes, and generally just out and about. The medium, which is his usual size, was just a bit tight for his liking, so we switched it out for a large and it's much more comfortable. Here's to a happy hub!!

This smartwool base layer is a must have for Fall and Winter in New England, perfect for layering to keep warm very comfortable for all activities

Everything about smartwool products is way above average. It's a bit pricey but well worth the money

You cannot go wrong with anything from Smartwool - for everyday wear and beyond.

Very comfortable and warm and the best base layer I've used. Wool does the best job wicking sweat and keeping me warm.

I usually wear this shirt under a suit jacket and it looks very nice. I am enjoying it a lot.

Use it as an insulating layer

Wear it a lot, wide heat range. I teach kayaking, cold early, warm afternoons. I have 3 of these.

Love the color

I love this, perfect fit, comfortable and cozy for all my outdoor adventures.

Love the quality & fit! I would buy again.
