How to Wash a BJJ Gi (and Keep It From Shrinking)

Short answer: Wash your gi after every session in cool or cold water, skip bleach, and let it air-dry or tumble on low. Always follow the care label first, because fabric and finish differ between gis.

How to wash a gi for the first time

Many gis are made of cotton or cotton blends, and cotton can shrink on early washes. Before you wear a new gi, read the care label, then wash it in cold water on a gentle cycle and let it air-dry or use a low heat setting. Wash it inside out so patches and embroidery take less friction, and wash it separately from items with zippers or hooks. If sizing matters to you, see our guide to choosing a BJJ gi size before you buy.

Cold water or hot water?

Cooler water is gentler on the fabric and on dyes and patches, and it usually limits shrinking. Hot water and a hot dryer are the most common reasons a gi comes out shorter in the sleeves and legs. If you need to kill odor, use a sport detergent or a small amount of vinegar in the rinse rather than turning up the heat.

Can you put a gi in the dryer?

Check the label. Many people hang the gi to dry, or use a low-heat tumble for a short time and finish by hanging it. A gi that goes into a hot dryer after every wash is more likely to shrink and wear faster. Never leave it wet in a gym bag, since that is how odor and mildew start.

Deep cleaning and odor control

  1. Hang or open your gi to air out as soon as training ends.
  2. Wash after every session. Do not wait for the weekend.
  3. Use a detergent made for sportswear if the gi holds smells.
  4. Dry it fully before you fold or bag it.

Making a stiff gi softer

New gis often feel stiff. Regular washing and wear soften them over time. Avoid fabric softener if the care label or the maker advises against it, since it can leave a coating on fabric.

Care for the rest of your kit

Your rash guard and shorts need the same routine. Read rash guard fit, care and sleeve length. If you are choosing a new gi, see Brazilian Jiu-Jitsu Kimono 1, Brazilian Jiu-Jitsu Kimono 2 or the Psalm 23:4 BJJ Gi.
