Big Agnes Pumphouse Ultra

The Big Agnes Pumphouse Ultra is a large-volume pump sack that inflates a sleeping pad by pushing air through its valve, saving the effort and moisture of blowing it up by mouth. Beyond pump duty, it works as a stuff sack for clothing or gear, and stuffed with soft items overnight it can double as a pillow. Since it relies on the pad's own valve, compatibility depends on having a pad with a standard inflation valve rather than a one-way or proprietary fitting - worth checking against your pad before relying on it as your only inflation method.
