Washing & Fit Guide for Karate Gi

New karate uniforms (usually 100% cotton) can feel slightly loose on first try-on. That’s expected: the fabric shrinks a little after the first washes and the fit settles. Use the quick fit checklist below, then follow the care routine and shrinkage guidance.

First try-on: quick fit checklist

• Jacket sleeves can be slightly longer at first (they’ll shorten after washing).
• Trouser length: try barefoot; legs may be a touch long before shrinkage.
• Run through a few basic moves (kihon): strikes, kicks, turns. No pulling or tight spots?
• Check waist & knot: firm yet comfortable?

What to expect: shrinkage & sizing

• Wash temperature: up to 30–40 °C to minimise shrinkage.
• Unbleached cotton: up to about 7% width and 10% length shrinkage.
• Sizing already accounts for this: after 2–3 washes most gis fit as intended.

Washing (routine)

• Before first use: wash without detergent.
• After each training: use regular detergent; avoid fabric softener and bleach.
• Turn the gi inside out to reduce wear.

Drying & ironing

• Air dry for best results.
• If you use a tumble dryer, expect an additional ~½ size of shrinkage.
• Iron on low/medium; avoid direct heat on prints/embroidery.
