Description

An all-season favorite, the Classic All-Season Merino Base Layer Long Sleeve can be sported as a base layer in the fall or summer when it's time to go backpacking. This base layer features Core Spun technology—which features Merino wrapped around a nylon core for added durability while still keeping the comfort of ultra-soft, responsibly sourced Merino next to skin. Our Raglan sleeves eliminate shoulder seams for perfect comfort under a pack, and smooth merrow stitching wraps from side to front to keep you looking as good as you feel.

  • Great Shirt
Size: Medium Color: Festive Fuchsia
I live in the high country in Colorado so wool is my best friend! Smartwool feels wonderful against your skin. When it's cold it keeps me warm; when its warm it keeps me cool. Merino wool is great since it doesn't require washing after each use and its better for the wool too. I love Smartwool products!!! ... show more

  • So comfortable and warm
Size: Large Color: Light Gray Heather
I love this Smart Wool base layer shirt. It doesn't itch against my skin and is really lightweight but cozy. My only disappointment is that it is made in China. I didn't know that when I ordered it...

  • Great ski base layer
Size: Medium Color: Light Gray Heather
Very lightweight, but kept me so warm while skiing. I ordered a small and medium because I am between sizes and ended up keeping the small. The material is thin and stretchy.

  • Love the Smartwool shirts
The Smartwool merino wool shirts are the best for the money. If you wear them while traveling, you can get a few days wear out of them before they need washing.

  • Light weight layer
This is a great color but I found the weight a little disappointing… I buy Merino and layer it to stay warm when I teach outdoors in the winter. This feels more like a summer tee than a winter insulation layer.

  • Warm, comfortable base layer for cold winter days.
Size: Medium Color: Black
I use this shirt as a base layer when I go hiking during cold winter months. It's comfortable, doesn't itch, and keeps me warm.

  • Fit and feel
I really like the fit and feel of this top. The material is very comfortable.

  • A tee for many occasions
Size: Medium Color: Light Gray Heather
This SmartWool tee is multi-functional - lightweight, takes up little room if traveling, good for many activities and with a scarf or necklace wearable to dinner out. I do recommend to go up to the next size if you want to wear it by itself. I bought a second one after wearing this one in Alaska in June. ... show more
