Size guide
Body measurements for every size we make, in inches and centimeters, plus how to measure and what to do between sizes.
The tables below are body measurements, not garment measurements. Find the row that matches your body, then check the fit of the piece you want. Each product page lists the garment’s own measurements on size M under Fit & feel.

Women’s bottoms run XS to XL. The inseam above is for full-length leggings and pants. The CoreFlex high-rise legging is a 7/8 length with a 25 in (64 cm) inseam. Shorts keep the same inseam on every size: 3 in (8 cm) on the run short and 6 in (15 cm) on the bike short.
How to measure
Use a soft tape measure and wear a thin layer, or nothing at all over the area you measure. Keep the tape level and snug, but not tight. It is easier with someone to help, or in front of a mirror.
- Chest or bust. Wrap the tape around the fullest part of your chest, under your arms and level across your back. Breathe out normally before you read it.
- Waist. Find your natural waist, the narrowest point of your torso, usually just above your belly button. Stand relaxed and do not hold your breath.
- Hip and inseam. With your feet together, measure around the fullest part of your seat. For inseam, lay a pair of pants that fits you well flat and measure from the crotch seam to the hem along the inside of the leg.

Between sizes
- Compression pieces (leggings, sports bras, base layers): size by your hip for bottoms and your bust for bras. Size down for a firmer hold, up if you want them easier to pull on.
- Regular fit: take the larger size if you plan to layer underneath, the smaller one if you want a cleaner line.
- Relaxed fit: these are cut with room already. If you are between sizes, take the smaller one.
