At the Expedition Idaho Adventure Race, Director Dave Adlard was surprised (and impressed) to hear that Team GearJunkie/YogaSlackers carried a pack-raft:
… For Idaho, we got more serious about our “flotation devices,” and we brought pack-rafts from Alpacka. The company makes a line of small, packable rafts that weigh as little as 3.5 pounds. But for Idaho, Alpacka built our team prototype rafts that were even smaller and lighter. The one-off “Ghost” model pack-rafts weighed an incredible 2.1 pounds each, and they rolled up small. …
Here’s how Pack-rafts inflate, are carried … and what happens when you get dumped into the river.
