Multi-density vented hood with ThermoBamboo inner lining, GlideSkin face seal, and comfortable contoured chin. Extended bib makes this hood ideal for layering. Inner neoprene lining with performance and environmental benefits. A blend of bamboo charcoal fibers and recycled polyester fibers provides excellent heat retention and helps improve warmth. A fully sealed, maximum stretch seam construction. Neoprene panels are glued and pressed together, then blindstitched (needle doesn't fully penetrate neoprene, keeping more water out).
