Granite Gear AirVent Reduction DryBlocs

AirVent Reduction DryBlocs by Granite Gear are ultralight waterproof roll closure bulk reducing sacks that are ideally shaped for easy and efficient packing. The extremely waterproof breathable eVent bottom allows air to escape as the sack is roll-compressed - yet maintains its wonderful block shape that is ideal for stacking in your pack. We also added an arched rolling stay that helps keep the top of the sack open while loading and shapes a perfect easy to grab handle when sealed. The ultimate cure for compression. Reduce weight and bulk.
