Sportful Hot Pack Ultralight Vest
Sportful's Hot Pack Ultralight vest offers you maximum protection and minimum bulk. Removed from your pack, it opens up to offer you total wind protection and a durable, washable, water-repellant fabric. Folded up it takes up only one third of a pocket. Either way, it weighs only 39 grams -- so light there's no reason not to take it along for the ride.
