A versatile sack for inflating your pad or protecting your gear.


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.

  • Timesaving: Inflates your pad faster than breath inflation. Easily snaps onto Therm-a-Rest valves.
  • SealLine® Protection: Built with ultralight waterproof BlockerLite™ material from our pals at SealLine, this dry sack is extra durable and features welded seams to keep your gear protected.
