Why leave behind a graveyard of half-filled canisters when you can combine them all with a gadget that weighs less than a penny? Born on the PCT in 2023, the Alpenflow lets you swap, share, or consolidate fuel like a pro. Borrow from a hiker box, split with a buddy, or finally finish off that pile of canisters in your garage. You can also portion off small amounts of fuel into a small empty canister so that you aren't carrying more than you need for short trips.
