Mystery Ranch® In and Out 18 backpack

When every gram counts, but comfort and practicality must not be left behind, the In and Out 18 comes into play. It packs down to the size of a water bottle, but when you unfold it, it shows it has more up its sleeve than just being ultra-lightweight. Ideal for quick trips, hikes and everyday wear where space and comfort matter.

Compact strength in action

Packing into its own pocket? No problem for this backpack. When it's not on your back, it disappears into a suitcase, a larger backpack or under a seat. Yet it has 18 liters of space, capable of holding water, a jacket, food and basic gear for the mountains or city. And it's no softie – despite its weight, it holds its shape and sits on your back like it's glued.

Fits, holds, doesn’t get in the way

Thanks to shaped shoulder straps and a chest strap, it fits snugly to the body. It doesn't get in the way, doesn't press and doesn't interfere. Breathable and low-profile padding ensures that your back stays ventilated even on summer days. Everything stays exactly where it should – whether you're going on a via ferrata or shopping.

Details that make sense

Elastic side pockets for bottles, a two-way zipper on the front pocket, outlets for a hydration pack or tool attachments – everything is where you intuitively look for it. Mystery Ranch just knows that details matter and every one counts here.
