Size guides list inches first, with centimetres alongside.


Garment measurements in inches, with centimetres in parentheses, taken flat. Waist values show unstretched and stretched measurements. Compare with underwear that fits you well. Allow 1–3 cm measurement variation. 2XL = XXL; 3XL = XXXL.

Cycling underwear with a shaped gel pad sewn in, worn under your usual shorts or pants. For relaxed rides, trips to town and the daily commute by bike. Unisex, for women and men.

Good for: relaxed rides and bike commutes when you want some cushioning without changing your outfit. The pad helps soften pressure and small bumps.
Not made for: wearing on its own as outer shorts. Comfort also depends on your size, saddle and riding position, so test the fit on a short ride first.


Check the length and the waist, both relaxed and stretched, in the size guide. The pad should lie flat, without folds, and the waist and legs should sit comfortably. Wash gently at 30°C as the care label says, and let it dry before your next ride.
