Topo Designs Mountain Cross Bag 17L – Unmatched Versatility for Every Adventure
Meet the Mountain Cross Bag by Topo Designs — a sleek, go-anywhere companion that blends smart organization with minimalist adventure style. Commute on the bike, hop a train, or head off for a quick weekend: this compact, versatile crossbody/shoulder bag adapts in seconds thanks to its removable straps and dialed layout. No more swapping bags between work and play — the Topo Designs Mountain Cross Bag keeps pace so you can focus on the journey.
Two exterior bottle holders, a padded 13" laptop sleeve, and intuitive pockets keep everyday carry dialed: notebook, charger, hoodie, camera, snacks — all easy to grab without rummaging. Light on your shoulder, tough on duty, it’s the do-it-all gear hauler for active city days and spontaneous escapes.


Eco-Driven Build, Trail-Tough Attitude
Built from 100% recycled nylon with a 200D ripstop upper and 1000D reinforced lower panels, the Mountain Cross Bag pairs low-impact materials with high abrasion resistance. Translation: less footprint, more lifespan. Inside, a recycled 210D liner slides gear in and out smoothly, day after day.
Ethically made in Fair Wear certified facilities with fabrics from certified dye mills, it’s a bag you’ll feel good carrying for years. The finishing touch? Heavy-duty YKK zippers and Topo’s MAP Guarantee™ repairs program — because gear should be repairable, not replaceable.
Streamlined Organization for Life in Motion
The layout is pure everyday practicality: a padded sleeve for most 13" laptops, interior mesh pockets for cables and smalls, and quick-grab storage for keys, sunnies, and travel docs. Outside, daisy chains and gear loops add modularity — clip a light, lash a layer, or attach an accessory pouch.
Wear it crossbody for mobility, shoulder-style for meetings, or hand-carry when boarding. From urban rides to trailheads, the Mountain Cross Bag is that rare piece that feels as natural at your desk as it does out on the dirt.
