Built to be your second bag on multi-day missions, the Packable Bullet practically disappears into your main pack so you can have it on hand for side missions and trips into town. It packs down to about the size of your hand and weighs next to nothing for easy storage no matter where you’re headed. And once deployed, the ultralight-yet-tough Ripstop Robic® fabric holds up to tough treks, while sealed seams and waterproof zippers keep your gear dry in a downpour.
