Tap through to see how the Sidekick carries across your routine — and exactly what fits inside.
Wallet, phone, earbuds, a water bottle, the book you're halfway through. The 9L holds what you actually use in a day — nothing you don't.
"I use this bag for everything — a purse, my carry-on personal item, my commuter bag for work, and a hiking bag for me and my dog. The pockets make it easy to find specific items, and the main compartment holds a book or tablet."
Every detail on the 9L Sidekick exists for a reason — because you asked for it in a review, or because we've been carrying one ourselves.
Interior sleeve fits a tablet or 13" laptop with room for a notebook alongside.
Tall, elastic pockets hold standard bottles up to 27oz so they don't tip out on the trail.
Water-resistant, tear-resistant, stain-resistant. Built to shake off a surprise shower.
Separate zipped pocket on the crown keeps lip balm, keys, or a passport where you can grab them.
Each bag repurposes eight plastic bottles. Recycled plastic hardware. Plastic-free packaging.
Covered against manufacturing defects for the life of the product. No receipt required.
Every bag we make is a small, deliberate trade — 8 plastic bottles redirected out of landfill and into a pack you'll actually use. And for every Sidekick sold, we fund the removal of one pound of trash from oceans and waterways.
It's a quiet kind of impact. Add enough quiet impact together, and it stops being quiet.

"This fits my MacBook Air in a soft case as well as a bike U-lock and my lunch when packed right. It's a great size if one travels light — and the outside bottle pockets are really tall and stable so they hold well."
"I've taken this backpack out on several outings now — beach trips, day hikes, picnics — and it checks all the boxes. It's lightweight, but sturdy; compact, but has tons of pockets for separating all of your essentials."
"For a day in the field this is just the right pack to have. Well made, great colors, and as always, gives our oceans a little help."
One pack. Four ways to live with it. Made from 8 recycled plastic bottles and backed for life.
