01 / READ THIS FIRST
Measure the garment, not your body.
Every measurement in the charts below is taken from the garment laid flat. The easiest way to choose is to measure a rash guard or pair of shorts you already like, then compare those numbers with the GRPL chart.
GRPL products are unisex and run large. Women and smaller male athletes will commonly start between Youth Large and Adult Small, depending on height, build and preferred compression.
Allow approximately 1–2 cm manufacturing tolerance. Height and weight can narrow the options, but chest, torso length, waist and fit preference should make the final decision.
02 / HEIGHT + WEIGHT STARTING POINTS
Start here. Confirm with the garment chart.
These ranges are practical starting points, not guaranteed fits. Two athletes at the same weight can need different sizes.
| Height | Weight | Rash guard start | Shorts start | Fit note |
|---|---|---|---|---|
| 150–165 cm | Under 60 kg | YL–YXL | YXL–S | Smaller adult athletes should begin in youth sizing. |
| 150–165 cm | 60–65 kg | YXL | S | A common starting point for women around 5′1″ and 60–64 kg. |
| 165–180 cm | 65–75 kg | YXL–S | S–M | Use torso length for the rash guard and waist for shorts. |
| 180–193 cm | 75–90 kg | S–M | M–L | Taller lean athletes often need length without extra width. |
| 165–180 cm | 90–105 kg | L–XL | L–XL | Chest, waist and preferred compression decide the final size. |
| 180 cm+ | 105–125 kg | XL–3XL | XL–3XL | Compare garment width and length before ordering. |

04 / HOW TO MEASURE
Lay your best-fitting gear flat.
Half chest
Measure straight across the rash guard from armpit to armpit. Full chest is double the half-chest measurement.
Front length
Measure from the highest shoulder or collar point straight down to the bottom hem.
Half waist
Lay the shorts flat without stretching the waistband and measure straight across the top.
Outseam
Measure from the top of the waistband down the outside edge to the bottom of the leg opening.
