'Fundamentals' Training Bag

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.

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. 😉
