FIND YOUR FIT

Made for the female body in motion.

Endurance wear designed around female athletes — drafted from the way a woman's body moves through swim, bike, and run, finished in original hand-drawn prints by founder Liz Tremain. Here's how to find your size.

HOW TO MEASURE

Three measurements. One soft tape.

Wear thin clothing or measure over a sports bra and shorts. Pull the tape snug — not tight. Measure twice if a number feels off.

01 — Bust

Around the fullest part of your chest.

Tape level all the way around. Arms relaxed at your sides, not lifted.
02 — Waist

Your natural waist — the narrowest point.

Roughly an inch above your belly button. Stand normally; don't suck in.
03 — Hip

The fullest part of your hips and seat.

Stand with feet together. Tape parallel to the floor, usually 7–9 inches below your waist.

BODY MEASUREMENTS

The size chart.

These are body measurements — not garment measurements. Match your body to the row.

Size	Bust	Waist	Hip
XXS	66-71	56-61	71-76
XS	71-76	61-66	76-81
S	74-81	64-71	79-86
M	79-86	69-76	84-91
L	84-91	74-81	89-97
XL	89-97	79-86	94-102
XXL	94-102	84-91	99-107

These body measurements work across our cycling, triathlon, run, and lifestyle apparel. Tri suits and swimwear include chamois and cut-specific guidance on each product page.

The full kit

A training bikini top that works across disciplines — pool laps, open water, bike and gym. The adjustable straps let you dial in the fit so nothing digs in across a long session. Pair with the matching bikini bottom for a two-piece training set, or wear under the tri jersey for a full training look.

Drafted for women, not adapted from men's. Every pattern is built from the ground up for the female body in motion — across swim, bike, and run.

True to size for most. Stay true for sprint and Olympic distances. Between sizes and racing 70.3 or full Ironman? Size up — long-course comfort beats compression every time.

Tri suits and swim cuts run snug on purpose. That's the compression and the hydrodynamics doing their job. Run and lifestyle pieces have a touch more ease.
