Swix Racex Merino Half Zip

The Swix Racex Merino Half Zip is a technical thermal undergarment made with RWS-certified merino wool blended with polyamide. Its naturally insulating fabric helps regulate warmth while wicking perspiration away from the skin for lasting comfort during demanding outdoor activity.

A half-zip closure lets you adjust ventilation as conditions change, while stretch cuffs provide a secure, comfortable fit. It is especially well suited to men who want dependable next-to-skin performance for Nordic skiing and other high-output mountain activities.
