Because it’s worn directly against the skin in conditions where sweating-through can have ride- ending consequences, a cold weather baselayer needs to feel luxurious and keep you dry. Our Transfer Wool Baselayer expertly does both thanks to the performance properties and super cozy feel of DriRelease® wool. Cotton-soft to the touch, this smart fabric leverages the wicking and insulating properties of natural Merino yarn that is wrapped around synthetic fibers. The result is a push-pull effect where moisture is pushed away from the body and heat stays in, leaving you with a strong foundation to tackle the most dynamic rides. The form fit design, longer cut through the torso, and thumb loops elevate this staple and make it ready to tuck, layer and go.

The key to staying comfortable on cold days is staying dry. We used a construction method called plating to place recycled polyester technical fibers next to skin on our responsibly sourced Merino wool, long-sleeve base layer.

The base layer uses a set-in sleeve design for a versatile form-following fit to make layering easy. - Transfer Merino fabric combines wool and recycled polyester for sustainable technical performance. - Unique plated fabric construction places polyester next to skin and merino on the exterior for superior moisture transfer and thermal regulation. - Made using fine 18.5-micron merino wool for superior comfort. - Recycled Repreve XS Polyester technical fibers are made from recycled plastic water bottles. - Set in sleeve construction for easy layering and versatility. - Wool Blend Performance certified by the Woolmark Company to ensure the highest quality product.
