Mystery Ranch just gave your go-bag a serious upgrade. Meet the In and Out series—two ultra-light, ultra-packable daypacks available in 18L ($89) and 25L ($99) sizes. These aren’t glorified stuff sacks. They’re fully engineered, featherweight packs built for summit pushes, spontaneous detours, and everything in between.

The In and Out 18 is your minimalist MVP. Weighing next to nothing, it compresses down into its own front mesh pocket—smaller than a water bottle—yet features contoured shoulder straps, a sternum strap, side water bottle holders, and tool attach points. Top-loading and hydro-compatible, it’s built for the fast and light crowd who still want smart functionality.

Need more space without the bulk? The In and Out 25 adds extra cargo room, a roll-top closure for weather protection, and the same compact stuff-into-itself capability. It’s the perfect grab-and-go option for travel, trail, or town—tough enough for summit days, sleek enough for daily carry.

Crafted from durable 100D Robic Ripstop nylon, both packs are designed to blend seamlessly into your luggage until needed, then deliver like a full-featured trail companion. Whether you’re jetting off for the weekend or chasing elevation, this is the kind of lightweight gear you’ll wonder how you lived without.
