Sizing Guide
Sizing varies a fair bit between brands, so use this as a starting point rather than the final word — ask us if you’re between sizes.
Clothing
Technical clothing generally follows standard adult sizing (XS–XXL) — compare against a piece you already own and fits the way you like. If you’re between sizes, sizing up is usually the safer choice for base layers worn under a harness.
Harness sizing
Harness fit depends on your height and torso length as much as your weight, and it’s the one piece of kit we’d always recommend trying before you commit, if you can. If you’re ordering without trying it on first, tell us your height and usual clothing size and we’ll help you pick.
Helmet sizing
Measure around the widest part of your head — just above your eyebrows and ears — with a soft tape measure, and match it to the table below. If you’re between sizes, most pilots size down for a snugger fit.
| Size | Head circumference |
|---|---|
| XS | 54 cm |
| S | 56 cm |
| M | 58 cm |
| L | 60 cm |
| XL | 61 cm |
| XXL | 62 cm |
| XXXL | 63 cm |
