Big Yella™ Backpack
Why We Built It
When you spend your day underground or on site, your gear takes a beating. The Big Yella™ was built to handle it — a hard-working, water-resistant backpack designed for industrial crews who need comfort, organisation, and visibility that lasts.
Developed and field-tested with crews working in real conditions across Canada, it’s designed by people who understand what it takes to keep gear dry, visible, and ready when it matters most.
Part no: HKIBYB
Field-ready and tech-tough.

Care & Maintenance
To Maintain the Product’s Performance and Durability, we Recommend the Following:
- Cleaning: Wipe the backpack with a damp cloth as needed. Avoid harsh chemicals or machine washing.
- Zipper Care: Zippers can clog up with dirt and debris over time, especially if you’re working in dusty or gritty environments. To keep them running smoothly, give them a proper clean and lubrication twice a year—or more often if you're on high-debris job sites. Use a toothbrush and some mild soapy water to scrub the zipper coils clean, then blow them out with compressed air to clear any lingering grit. Once dry, apply a light coat of silicone spray, beeswax, or a zipper-safe lubricant to keep things moving.
- Avoid Heat and Sharp Tools Near the Zippers: Extreme heat or contact with sharp objects can permanently damage your zippers. Once a coil is nicked, melted, or cut, it can’t be fixed. A common cause of damage is storing tools blade-up or edge-out—make sure anything sharp is packed with the business end pointed down and away from the zippers.
- Proper Use: Fasten the buckles properly and adjust straps to fit securely and comfortably on the wearer. Avoid dragging backpack or snagging seams on sharp objects. The Big Yella™ is built tough, but forcing in too much gear can put unnecessary strain on the zippers. If you’re struggling to close the bag, it’s a sign it’s overloaded. Repack or lighten the load to avoid causing the zippers to separate or fail over time.
- Storage: Store in a cool, dry place when not in use to prevent exposure to extreme conditions.
