The Thermarest BlockerLite Pump Sack is an ingenious inflation solution for your Thermarest mat. It is essentially a roll top dry bag with a valve on the end. Connect the valve to the one on your mat, open the bag out then close the top and squeeze the air in to your mat. No batteries required, it works in all weathers and conditions and saves you blowing lung fulls of damp air into your mat.
The BlockerLite also doubles as light weight waterproof 20 litre dry bag for storing your gear in when its time to break camp.
