01 — The stripes

Two stripes, all the way down.

A pair of accent stripes runs from the sleeve hem down the outside of the body and out along the leg line. They are cut and stitched in, not printed, which is why they stay straight where the fabric curves around the ribs.

02 — The back

Open at the shoulder blades.

An open triathlon back: the shoulders and sleeves stay covered while the centre drops away. You keep the sleeve without the heat, and the arms move freely through the stroke.

03 — The leg

High cut, bound edge.

The leg is cut high and the opening finished with a bound edge in the accent colour, the same binding used at the sleeve and around the back. Satin spandex throughout, skintight, mesh-lined through the gusset.

Swimsuit

Our sizes run small. Our swimsuits are cut for a skin-tight fit. The finished piece measures smaller than your body and stretches to fit on the body. Do not order down. The swimsuit will not fit.

Height and girth decide your size. Girth is the loop from your shoulder, down through the crotch and back up. On a swimsuit it is what keeps the leg line from riding and the straps from pulling. If both fall within the same size, that's your size. Chest, waist and hips confirm the fit.

Between two sizes? Check your girth. If it is above the smaller size's range, take the larger size.

Centimetres are our working measurements. Inches are rounded to the nearest half.

How To Measure

Getting a garment that fits well starts with accurate body measurements.

Please compare your own measurements carefully to those of the size table. If you are off this chart or between sizes it is highly recommended to order our items made to measure to get an optimal fit.

Do not order a smaller size than actually needed. Our sizes run small and the garment will be too small. More information regarding sizes can be found in our FAQ.

1. BODY HEIGHT
Your body height when standing flat on the ground (as outlined in your ID document).

2. TORSO MEASUREMENT
Starting at one shoulder, wrap the measuring tape down your body, between your legs right against the leg crease, bringing the tape up your back to the point where you started.

3. CHEST MEASUREMENT
Measure around the fullest part of your bust straight across the back.

4. WAIST MEASUREMENT
Measure around your natural waist (smallest part of the waist).

5. HIPS MEASUREMENT
Stand with your heels together using a tape measure around the fullest part of your hips and rear. Use a mirror standing sideways to ensure you are at the fullest point.

6. INSEAM
Measure from the center of your crotch down the inside of your leg until the ankle bone.

Gloves

Gloves are cut close. The finished glove measures smaller than your hand and stretches to fit. Measure your dominant hand.

Hand length and hand circumference both decide your size. Measure the circumference around your palm at the knuckles, and the length from the base of your palm to the tip of your middle finger. Both need to fall within the same size.

Outside the ranges, or falling into different sizes? Choose made to measure in the glove size options above.

Centimetres are our working measurements. Inches are rounded to the nearest quarter.
