BJJ Backpack Size & Rank Guide

Choose the backpack size that fits the way you train, then select the belt-rank straps you have earned. The backpack color and rank straps are chosen separately, so any white, blue, or black bag can be paired with the appropriate available rank.

Which Graded Backpack Size Is Right for You?

Choose the Rank You Wear Today

Your rank straps should match the belt you currently wear. Bag color does not determine rank: for example, a blue backpack can be ordered with black-belt straps, and a black backpack can be ordered with blue-belt straps.

Frequently Asked Questions

Does a backpack include rank straps?

Yes. One pair of the rank straps selected on the product page is included with each interchangeable Graded Backpack.

Can I choose any bag color with my rank?

Yes. White, blue and black are backpack colors, while the second selection is your current belt rank. Choose them independently.

Do replacement straps fit the original Graded Backpacks?

No. Replacement straps are made for the interchangeable-strap models and are not compatible with the original fixed-strap edition.

What if I am between the two sizes?

Choose the Large if you normally carry an adult gi, towel, change of clothes or work items. Choose the Small if you prefer a compact load or are buying for a youth athlete.
