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

I have been wearing 'performance' base layers for years. I have not been impressed...until this. Boundary Waters canoe trip in May. I slept in my base layer, got out of my hammock, paddled and fished all day. Total comfort!

Great base layer when it's cold

Excellent base layer!

Love the weight, wear it year round

In the Fall of 1975, I had the experience of getting caught in rogue weather in the Eastern Sierra and I developed hypothermia. I have been cold ever since. The Smartwool base layer products are a wonderful way for me to stay comfortable. I have a number different temperatures depending on the situation. For the quality and functionality, the prices are more than fair. I have some pieces that are 20 years old and have not shown any appreciable wear or tear.

Love this shirt love the colors very comfortable very well-made and love the hood!!!

My husband loves this shirt. It's light enough to wear year round! I would buy this product again.

My favorite base layer perfect for XC, cycling, running.

Great shirt love it wear it all the time

Always love smartwool base layers. I use them for camping and always stay warm. They fit well and are excellent quality.

This shirt is my favorite for those in-between days when I need more than a T-shirt but lighter than a jacket. I've worn it for years, and it's perfect from fall to spring!

Comfortable well fitting top worn comfortably under a light sweater.

Works great for skiing and I like it better than polyester. Great to get this on sale.

Great baselayer, not itchy at all after a wash. Wish it had thumbholes, but it's also nice that it doesn't get in the way of my watch

Smart wool products that I purchase I use them for outdoor activities and leisure in all types of weather just about every day! Great products

I wear this shirt for year round because it provides sun protection and is comfortable in all temps.

I have several All-Season merino base layers. They are truly an all year round shirt for me living int he dee[ south, Louisiana. I made this purchase for the color.

Smartwool is hands down one of the best base layers I have used. They are lightweight yet keep me very warm. Good value for the money.

I was very pleased with how well they fit. I'm now thinking about buying more when I get enough to pay for them. Thank you so much!

All day, all seasons!

I love both the All Season and Classic version of Smartwool's Merino Base Layer tops. I were this alone on warmer days or under a sweater or colder day. Soft. Be careful too avoiding shrinking these tops. After making the mistake of putting it into a dry, I learned to hang dry. It is dry in no time at all.

Great lighter weight base layer. Wear it under a warmer layer for riding and will be great for camping or need something light weight with sleeves in the summer.

I've been wearing the All Season shirts for years. I'm 5'10", 170 lbs, 41" chest, 32" waist and the medium fits like it was tailored for me. I wore one for over 1k miles of the PCT and it held up extremely well for a merino shirt. You have to expect thinning with Merino as a natural fiber so adjust expectations, but the benefits far outweigh the shorter life span of a synthetic shirt. They hold their shape under a pack day after day, the nylon core really extends the lifespan and provides the durability without sacrificing the incredible feel and anti-stink that merino provides. It dries quick enough thanks to no spandex content. The only downside worth commenting on is the stitching seams along the shirt will fray pretty bad over time as they rub on the backpack etc. It doesn't effect functionality and I just carefully trim or remove with a fabric shaving device at a setting that doesn't get to close to the fabric, works well. I've been wearing merino for many years from Icebreaker, Ibex, etc and Smartwool has nailed it. If anything, i would suggest experimenting with higher nylon content for added durability, maybe in targeted high-wear areas. I love Smartwool boxer briefs but the crotch wears through eventually while the rest of the boxer had plenty of life. They should be made with 100% nylon breathable mesh and slightly higher nylon content throughout and they would have a gold standard boxer by which all others are measured! Please make them Smartwool

I work construction and this keeps me warm and toasty

This base layer is great for being out in the field clearing trees from the trail especially during cold and wet days. These are comfortable and provide me just right amount of warmth without restricting movement.
