Therm-a-Rest BlockerLite pump sack

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.

• Versatile: Doubles as a lightweight 20-liter dry sack when it’s time to hit the trail.
• Not compatible with Classic Valves (valves on pads pre 2020).
