Smartwool Merino 150 Baselayer Long Sleeve Top

From taking the chill out of cool morning bike rides to hiking to the summit of Quandary Peak, you need a versatile layer that works as hard as you do.

The year-round Smartwool Merino 150 Baselayer Top is up to the challenge thanks to the body temp regulating properties and breathability of Merino. Featuring Core Spun technology, the top includes wrapped Merino around a nylon core for added durability while still keeping the comfort of ultra-soft Merino next to the skin. Smartwool added smooth flatlock seams to help minimise chafing and offset shoulder and side seams to lie smoothly beneath pack straps. Performs well on its own in warmer temps or layers up easily when cooler weather rolls in.

Smartwool's lightest, most versatile layer with enhanced durability and ultimate breathability. Quick drying, it works as a solo layer in warm weather or as a baselayer in cool weather. Merino fibers wrapped around a nylon core for added durability while still keeping the comfort of Merino next to skin fit.

When washing your product you want to place it on a warm, gentle wash. Do NOT bleach, tumble dry, iron or dry clean.
