Review: Zenbivy Dry Sack

Say goodbye to the heavy, unwieldy, duffel-like drybags of yore; with the Zenbivy Dry Sack, you get waterproofness, light weight, and compressibility all in one. With its built-in valve, this super-slim but surprisingly durable stuff sack can cinch down your sleeping bag while backpacking, safeguard a blanket while car-camping, and keep essentials dry on a river trip. Three sizes— 7, 10, and 15 liters—mean you can keep the moisture away from summer and winter bags alike, every season of the year.
