A Dry Bag That Filters Water And Inflates Your Sleeping Pad


Whether you are thru-hiking, bikepacking, or on some other ultralight pursuit, multi-functional gear is key. The Bitterroot dry bag fits the bill, performing three different functions in one lightweight and compact system — it will keep your gear dry, filter water, and inflate your air mattress.

Designed by lifelong outdoorsman and veteran with 23-years service Jason Evett, the Bitterroot 3-in-1 dry bag is an 18-Liter bag made from 200 denier nylon — a National Sanitation Foundation (NSF) approved water potable material.

When paired with Aquamira’s Frontier Max (included), you will have virus level water filtration no matter where your adventures take you. In a gravity-fed configuration, the Bitterroot will filter a liter of water approximately every 3 minutes (times may vary depending on the amount of sediment in the water). Prime the filter with a few pumps of the bulb and let the system work hands-free thereafter.

And when you’re finished, turn the bag inside out and shake the water off. The hydrophobic material will dry in an instant allowing you to put your important items back under cover.

At the end of the day, the Bitterroot can be used to inflate your sleeping pad. Simply attach the black quick connect hose to the bag and the other end to your mattress, trap air inside the Bitterroot and roll down the bag to inflate.

The Bitterroot dry bag weighs 5.2 oz and with everything included (bag, filter, and hoses) it weighs 12.5 oz.

Airborne Outfitters is taking pre-orders for the Bitterroot 3-in-1 dry bag over on Kickstarter. You can get one at an early bird price of $85-$100 with expected delivery in July. The company will be selling them for $145 from their site eventually.
