Most practitioners learn to fold a BJJ gi by copying whatever their training partners do, which means most people are folding it slightly wrong — usually in a way that creases the collar or crushes the lapel over time. The traditional fold takes under a minute once you know it, keeps the gi compact enough to fit in a normal gym bag, and avoids the sharp creases that weaken stitching at the collar and cuffs.
Step-by-step: folding the jacket
- Lay the jacket face-down on a flat surface, collar at the top, exactly as you'd lay it out to put it on.
- Fold each sleeve inward toward the center of the jacket, keeping the fold along the shoulder seam rather than partway down the sleeve.
- Fold the jacket into thirds lengthwise — left side in first, then right side over it, so the final shape is a long rectangle roughly one-third the original width.
- Fold that rectangle in half from the bottom hem up toward the collar, giving you a compact square or rectangle depending on gi length.
Step-by-step: folding the pants
- Lay the pants flat, legs together, waistband at the top.
- Fold in half lengthwise so one leg sits directly on top of the other.
- Fold into thirds from the waistband down, matching the width of the folded jacket so everything stacks evenly.
Putting it together
Place the folded pants on top of the folded jacket, then wrap your belt around the entire stack — this is the traditional method used in most academies, and it does double duty: it keeps everything compact for the gym bag, and it prevents the fold from loosening in transit.
If your gi is still damp from the last class, don't fold it tightly for storage — even a few hours folded while damp can set a mildew smell into the fabric that's difficult to wash out. Let it air out fully first, then fold.
Why the fold actually matters
Beyond convenience, the traditional fold avoids two specific problems: collar creasing, which over hundreds of washes can weaken the reinforced stitching around the lapel, and uneven wear on one side of the jacket, which happens when a gi gets stuffed into a bag unfolded and ends up crushed asymmetrically wash after wash. A gi folded the same way every time wears evenly and holds its shape longer — which matters more the more expensive the gi.
