Traditional "waterproof" gloves quickly get heavy as water loads between the shell fabric and the waterproof liner. OutDry is different. OutDry is a patented construction technology that bonds a waterproof-breathable membrane directly to the shell fabric. There's no gap to load with water so gloves stay light and dry. And with no extra layer of water, gloves breathe better and stay flexible.
