Top-rated water protection stuff sack doubles as a convenient pump sack for inflating your Therm-a-Rest pad.

Thermarest says:

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.

The BlockerLite Pump Sack is a fantastic option for weight conscious backpackers who need a large capacity waterproof stuff sack and also need a pump sack for their Therm-a-Rest sleeping mate. The is a great piece of kit that combines the high performance fabric from SealLine that gives durable waterproof protection with the practicality of a pump sack that works on both WingLock and TwinLock valves used on Thermarest mats.

Used as a stuff sack, the 20L capacity is a really good amount and I've never needed more for a single dry sack when out on expeditions. When used as a pump sack it fits easily and securely over the valve and obviously saves you a lot of time and effort when inflating your sleeping mat at the end of the day. A great two-in-one idea that is very well made.
