SmartWool Merino Sport 250 Long Sleeve

Features

The men's SmartWool Merino Sport 250 Long Sleeve crew neck is a purpose-built cold-weather running layer.

Designers cut the Sport 250 Long Sleeve from a Merino-polyester blend that combines the benefits of both: breathability and temperature regulation from Merino with the quick drying time and durability of polyester.

Thumbholes on the sleeves let you lock in the warmth, and an athletic fit sticks closer to your body for better layering. Plus, reflective elements make you easier to spot in low-light situations.

With body mapped mesh that increases breathability in key areas, the men's SmartWool Merino Sport 250 Long Sleeve will let you stand up to Mother Nature.
