Our Buckhorn Snap Shirt blends brushed organic cotton with recycled Thermore® Ecodown® synthetic insulation.

Our Buckhorn snap shirt blends a brushed organic cotton exterior with recycled, Thermore® Ecodown® synthetic insulation on the interior. The lofted insulation is mapped—more in the core, less in the arms—to dial up just the right amount of warmth without excess bulk. Made for working out back or heading for the ski hill, it adds characteristic Stio® detail with custom snaps and an embroidered Pinecone logo. The polyester lining slides smoothly over base layers, wool sweaters or cozy fleeces.
