Size Guide
Our kit is cut for running: close where it needs to stay put, roomy where you need to move. Measure yourself once, then use the charts below. Between two sizes? Go up.
How to measure
Use a soft tape measure and wear light layers. Keep the tape level and snug, but not tight.
- Chest. Measure around the fullest part of your chest, under your arms and across your shoulder blades.
- Waist. Measure around your natural waist, the narrowest point above your belly button.
- Hips. Stand with your feet together and measure around the fullest part of your hips.
- Inseam. Measure from the crotch seam down the inside of your leg, or take it from a pair of shorts that already fit well.
