Smartwool Classic Merino Base Layer 1/4 Zip

Smartwool Classic Merino Base Layer 1/4 Zip

The Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip is one of Smartwool's heaviest base layer tops, updated with a slim fit and improved seams. A 10 inch quarter zip lets you dump heat fast on hard efforts without stopping to pull off a layer.

Why We Carry It

It's the base layer we recommend for cold, high output days on the skin track or trail, when you need warmth and a quick way to vent.

Highlights

• 100% merino wool: Interlock knit that regulates temperature, moves sweat and resists odor.
• Thermal 250 weight: One of Smartwool's warmest base layers.
• 10 inch quarter zip: Open it on the climb, close it for the descent.
• Slim fit: Follows your body so it doesn't bunch under a midlayer or shell.
• Flatlock, offset seams: Shoulder and side seams sit away from pack straps to prevent chafing.
• Natural odor resistance: Stays fresh over multi day trips.

Best For

Skiing, ski touring, cold weather hiking and running. Made for skin laps up Monarch Pass.
