For lightning-fast inflation and water protection, the BlockerLite Pump Sack gives you a versatile and lightweight option for gear storage and mattress inflation. Designed with our friends at SealLine, the pump sack features durable and welded seams. Big enough to hold 20-liters of gear, it’s the perfect size to store extra clothing before inflating a high-volume air pad that features the WingLock or TwinLock valve.
