When the tail end of autumn sends frigid weather your way, stay as warm as your prey in this super-insulating Omni-Heat liner jacket. It features 100 grams of our progressive thermal insulation, which has a soft and light down-like feel combined with the highest heat retention per gram in the industry.  The zip-in Interchange system allows you to combine this with the corresponding shell for even more foul-weather protection. Shorter length is ideal over waders. Zip-closed hand pockets and a chest security pocket provide easy-access storage for shells, snacks, and other survival items. Relaxed fit.
