When heading to and from the water during winter surf sessions, we fight the chill with Katin's OTG Yukon Puffer Jacket. The compressible down insulation traps warm air inside and stuffs easily into our pack when we're headed into the surf, while the waterproof backer and fully sealed seams stop our wetsuit from soaking the lofty fill when we shrug back into the warmth at the end of our session.
