Men's Smartwool Shirts

Merino wool is a natural, durable fiber grown on Merino sheep. The breed is known for its very fine, soft wool, which is what Smartwool uses to craft each piece it makes.

Unlike the old, scratchy wool sweaters you might be used to, Smartwool's Merino is super soft next to skin, helps naturally regulate your body temperature, wicks sweat away quickly, helps to provide UPF protection, is fire-resistant, biodegradable, and won't stink when you start sweating. Basically it is the perfect piece for any adventure.

When you buy Smartwool products, you can be sure you're getting a lightweight and long-lasting performance piece that will help you perform your best no matter the weather.
