The snowmelt bag is an innovative design that allows the user to fill, melt, and filter up to 3L of snow at a time. With a rechargeable 12V battery and resistance heating system, the system can deliver clean drinking water within 30 minutes of use. The 3000 mAh battery delivers enough power for 6L of melted water and can easily be recharged at home or on the go. The multilayered bag provides a water resistance synthetic layer and insulated inner layers that keep the elements out and the heat in. The product's filter system keeps you safe while giving you the flexibility to filter water through gravity, pressure, or suction through an attached mouthpiece. Look for Snow Melt to be your solution to outdoors clean water in the wintertime!
