The Hybrid Jacket is where technology meets function and then has a baby named AWESOME! A windproof and water-resistant outer-shell and a HexLite Fleece interior for warmth get the Hybrid started. Then we introduced Xeolite (lava rock) and coffee into the fabric for the best in scent containment technology. Reinforced "high stress" areas and compressible sleeves complete this little miracle of science. It’s your next favorite piece of gear, trust us.
