There’s something to be said for having a day pack in your larger luggage—like when you’re walking over to boulder half a mile from your campsite in the woods. The stuff-sack weight Antimatter Pack stuffs down into its own pocket so it’s easy to throw in. Airy mesh straps keep it breathable when the going gets steep, side compression straps cinch down your load, and two water bottle pouches hold the day’s agua.
