Thermarest BlockerLite Pump Sack Outdoor accessory

Amazon

Versatile bag for inflating the mat or protecting equipment. Time Saving: Faster than manual inflation. Easy to snap into valves of Therm-a-Rest. SealLine protection: This pack sack is made from the same particularly light and waterproof BlockerLite(TM) material as the pack bags from the SealLine range. It is therefore particularly robust and protects the contents thanks to welded seams. VERSATILE - Once the tent camp is dismantled, it can be used as a waterproof pack sack with 20 litre capacity.

For lightning-fast inflation and water protection, the Thermarest BlockerLite Pump Sack gives you a versatile and lightweight option for gear storage and mattress inflation. Designed with 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 Thermarest NeoAir pad that features the WingLock or TwinLock valve.
