Inflation bag
Also: inflation bag, pump sack
The inflation bag is a light nylon bag you use to inflate a packraft in a few minutes, without any pump.
- 1Capture air with the open bag
- 2Put the bag on the valve and squeeze
- 3Finally top up by mouth
Here's how: pull the bag through the air with the opening open so it fills, twist the opening shut, put the bag on the valve and squeeze the air in. Repeat a few times and top up by mouth at the end. Many inflation bags double as stuff sacks.
The Anfibio blog mentions an extra benefit: sleeping mats can also be inflated this way without moisture from your breath getting inside.
