Our Flex fabric might be from the future. With a luxe, weighty drape, mind-blowing softness, and a laundry list of performance benefits like temperature regulation, UPF 50, and four-way stretch? Yeah, definitely from the future. A transitional season go-to, the Bamboo Flex Quarter Zip makes for an absolute layering workhorse. Pair it with our Tradewind Pant when you're out there working on your backswing, or layer it beneath your winter shell when you hit the slopes.
