Product Customer Reviews

When I am cycling I want comfort on the saddle and for the legs to stay in place I want NOTHING constricting around my waist, nothing. Females actually have hips that stop wardrobe malfunction we don't need clothes to slim our waists whilst we are sat down. Can you actually make some padded shorts for women with comfort first. That would be great.
Amazing difference so comfortable no more agony on the spin bike best fitness buy thanks Decathlon
Good quality shorts. Better if there is thicker cushion. Used for 6hrs cycling can feel numbness kicked in.
Perfect fit for me! Good material and comfortable wear.
doporučuji, velmi příjemné na těle a kvalitní vložka.Nosím je jen tak s delším cyklistickým tričkem, i když je psáno jako spodní kraťasy. V létě jsem jich hodně využila a více si opálila i nohy ♥
Ok, aber etwas zu breit im Schritt
Bequeme Hose, angenehm zu tragen, könnte etwas kleiner sein
Hätte etwas dicker gepolstert sein können
Gracias!

La tela es fina y transpira bien. A la hora de hacer ejercicio no se siente oclusivos ni tampoco da calor. La cintura ajusta sin apretar. Yo lo uso para hacer spinning en casa pues se transparenta. La parte mala es que la pernera se remanga a pesar de tener silicona y en principio ser para evitar esto.

Undershorts support
We wanted to provide the support you need, even without straps. That's why these close-fitting undershorts have a wide elasticated waistband that adapts to you and stays in place, without requiring any adjustments.
A 2nd skin with comfort to boot.
This pad is designed for regular users. The support foam is soft with medium firmness. Provides good user comfort and protects the cyclist's pressure zones for rides of up to 3 hours. Foam thickness: 13 mm Foam density: 220.5 lbs/m³ Foam firmness: 25 KPa
Shorts, undershorts
Undershorts are to MTB what kilts are to Scotland: you wear them against your skin! To avoid chafing, we therefore recommend changing them and washing them as if they were underwear. And when you're riding, your shorts and undershorts should never be attached. Why? Because each has their own role to play: - The undershorts stay in place for comfort and support. - The shorts move with you for better freedom as you cycle
