Built with Woolverino Core-Spun Technology, this quarter zip wraps soft merino wool around a durable nylon core.

The 4% spandex adds comfortable give that pure merino can't match.

Why Core-Spun Merino?
Traditional merino is wonderful but fragile. Core-spun technology solves that problem by wrapping merino wool around a nylon core. The merino stays against your skin where it belongs, delivering natural temperature regulation and odor resistance. The nylon core adds strength and elasticity that pure merino can't match. Combined with 4% spandex, this fabric moves with you through any activity and bounces back wash after wash.
