The Sustainable Commuter Bag Checklist: 8 Must-Have Features City Riders Swear By in 2025
It's 7:45 AM. You're running late. Coffee in one hand, phone in the other. You dodge puddles, squeeze into a packed train, and by the time you get to work your back’s soaked, your laptop’s scratched, and you're one "Where’s the file?" away from spiralling.
2025 commuting is wild. But the right bag? That’s your daily defense.
This isn’t just a checklist, it’s your survival guide. These are the 9 commuter-bag features real riders swear by. The Square Backpack checks every single one.
1. Laptop Safe Compartment
A 15” laptop shouldn’t need a hiking pack.
The Square Backpack's dedicated padded sleeve fits your laptop snugly, alongside a tablet, charger, A4 notebooks, power bank, and more — all while staying slim on your back.
2. Collapsible and Expandable Structure
Folds nearly flat when empty. Snaps open to hold 15L when you need it. No unnecessary bulk. Just smart volume control for busy days and light days alike.
3. Made from Recycled Bottles with Waterproof Coating
Made from 100% recycled PET bottles with a PU coating for water resistance. Around 12 bottles go into every Square Backpack. Keeps plastic out of landfills and rain out of your gear. Done with your bag? Kiwee’s got you. Send it back and we’ll recycle the materials responsibly.
4. Convertible Strap System
Wear it your way. Backpack or crossbody, the Fasten & Go straps adjust to your lifestyle. Light on your shoulders, easy on the eyes.
5. Smart Internal and External Pockets
Every inch of the Square Backpack is designed with purpose. Inside, there's a dedicated slot for your water bottle so it doesn’t tip over and soak your gear. A mesh zip pocket keeps small essentials like keys or earbuds in check, while a padded sleeve secures your laptop without wobble.
On the outside, a quick-access side zipper lets you grab your phone or wallet in seconds, and a hidden zip pocket tucked behind the back panel adds an extra layer of security for valuables. Everything has a place and that place makes sense.
6. Power Bank Pocket with Cable Port
Plug your charger into the built-in pass-through hole while your phone stays in your hand. Power up on the move without digging through zippers.
7. Lightweight Yet Structured
Weighs only 650g, but carries like a pro. The frame holds its shape without heavy foam, making it ideal for fast-moving, on-the-go routines.
8. Three Sizes, Same Style
Choose your fit:
- Small (13") – 10L, 560g
- Medium (15") – 15L, 590g
- Large (16") – 18L, 650g
Bonus: Plastic-Free Packaging
Every Kiwee backpack ships in a plastic-free recycled cardboard box. No bubble wrap. No waste. Just clean, thoughtful packaging you can actually recycle.
Built for the City, Built for You
This isn’t just a bag.
It’s part of your daily rhythm. A lightweight workhorse made from waste, shaped for the city, and built to last.
