Fit guide

Sizing & fit

Every measurement below is a body measurement in centimetres, not a garment measurement. Measure once, size once. If you sit between two sizes, the sport-specific notes further down tell you which way to go.

How to measure

Chest
Around the fullest part, arms relaxed at your sides, tape level under the armpits.
Waist
Around your natural waistline where you actually wear shorts — not pulled tight.
Hip
Around the widest point of the seat, feet together.
Hand
Around the knuckles excluding the thumb, hand open and flat.
Shin
From the centre of the kneecap down to the top of the ankle bone.

Tops, rash guards & layers

Applies to rash guards, compression tops, tees, tanks, hoodies, crewnecks, jackets and the walkout robe. Compression pieces are cut one step tighter than the tees by design.

Shorts, spats & joggers

Waist figures are body measurements. The last two columns convert to the sizing you may already know from other fight brands.

Gloves & hand wraps

Measure around your knuckles with the hand open. Hand wraps are one size (4.5m) and fit the full range below.

Shin guards

Fit shin length first. If your calf sits in a larger band than your shin length, take the larger size — a guard that pinches the calf will rotate.

Recommended fit by sport

No-Gi & Grappling

  • Rash guards and compression tops: take your true size for a second-skin fit. Between sizes, size down — the knit has high recovery and a loose rash guard gets gripped.
  • Spats: true size. Size up only if you are over the height range for your chest size.
  • Grappling tee: relaxed cut, take your true size; size down for a closer line.

MMA

  • Fight shorts: match the relaxed waist measurement, not your jeans size. The velcro-plus-drawstring closure covers roughly 6cm of adjustment.
  • Compression shorts under fight shorts: true size, never up.
  • Gloves and shin guards: measure hand circumference and shin length rather than guessing from body size.

Muay Thai

  • Muay Thai shorts run traditionally roomy through the leg. Take your true waist size — do not size up for the classic look, the high-cut leg already provides teep and knee range.
  • Boxing gloves for clinch and pad rounds: 14–16oz if you spar often, 12oz for bag and mitt work.
  • Shin guards: choose by shin length first, then calf circumference.

Boxing

  • Boxing shorts: true waist size, wide elastic band gives about 8cm of stretch.
  • Gloves: 12oz for bag and mitt work, 14oz general training, 16oz for regular sparring above 75kg.
  • Hand wraps are one size — 4.5m semi-elastic suits hands from 17cm to 25cm circumference.
