Fundamentals Performance Backpack

"Fundamentals done well are advanced."

Minimal in design, maximum in function. The Fundamentals Backpack is built for those who move with purpose, whether you're heading to training, the gym, or life on the go. Sleek, water-repellent, and deceptively spacious, this pack keeps you prepared for anything while staying grounded in your values.

Crafted from 100% recycled polyester, it’s tough on the outside and thoughtful on the inside....just like the Bushido spirit.


Built for Function

Durable & Water-Repellent
Made with recycled poly fabric that resists the elements and keeps your gear dry, day in and day out.

Comfort Meets Carry
Padded, adjustable shoulder straps and a sturdy grab handle make it easy to carry however you move.

Simple, Smart Design
Large main compartment with drawcord closure for quick access to your essentials.


Spaces with Purpose

  • Rear padded laptop sleeve (fits up to 16")

  • Two side pockets with magnetic closure

  • Two front zipped compartments for easy access

  • Rear zip security pocket to keep valuables safe

  • Rear luggage strap for travel-ready utility

  • Self-coloured PU zip pulls for a clean, minimalist finish

  • 21L capacity that’s gym-tested and everyday-approved


Tested by Us

We load it up ourselves; gloves, headguard, Thai shin pads all fit comfortably in the main compartment.

Gumshield and tiger balm slid right into the front pockets.

Side pockets held our tape and water bottle with ease.

Did we test it with a laptop too? No, because we don’t take laptops to training… but it does fit one. 😉
