The Low Loft Jacket combines a tight woven 4 oz/yd, 100% nylon face fabric with Brookwood Balloon™ 70 Denier nylon ripstop fabric. This is the next generation of the wildly popular consumer lightweight low loft jacket. This low loft provides superb all weather protection with enough air permeability to dramatically reduce the balloon effect when you have to rapidly stow the jacket. This highly breathable jacket expands the comfort across a broad temperature range and allows for baking dry damp inner layers.
