Tribesports’s Size Guides are of body measurements only, not garment measurements. We encourage you to measure yourself before choosing what size to buy, as sizes between brands can vary wildly.

How to measure yourself:

Waist: This measurement is taken as a circumference measurement around the waist just above the belly button. Stand in a relaxed posture and breath out. Place the tape measure around your waist t the narrowest part just above the belly button, keeping the tape horizontal.

Hips: This measurement is taken as a circumference measurement around the widest part. Stand with your feet together and place the tape at the fullest point on the hips, keeping the tape horizontal.
