Product Customer Reviews

Amazing difference so comfortable no more agony on the spin bike best fitness buy thanks Decathlon
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.

Je suis très satisfait de ce sous short. Je le porte pour mon vélo d'intérieur et il est confortable et rembourré aux bons endroits. Le rembourrage est également discret et, bien qu'il s'agisse d'un sous short, il est agréable à porter seul. A recommender fortement!.
Plus de grande taille chez les femmes
A fait son job pour ses 2ère heures sortie en VTT
Je n'avais pas vu que c'était un sous-short femme, il me convient très bien. La coupe est très confortable et le gel très performant.
Confortable.
Bien pratique pour mettre sous un short long ou court ... Pas encore utilisé pour faire du VTT ...
Bien
Après avoir essayé plusieurs model et pour un premier cuissard c'est celui ou je me sentais le mieux
Bon produit.
Très bon produit ,fait le taf
C’est vraiment un super cuissard ayant pas mal de legging je peux le porter avec tous c’est confortable plutôt discret je vais en racheter un 2 ème sans hésitation
Je prends un cours de vélo d’une heure trente. Ce sous-short me permet de passer le cours tranquillement malgré les coups que je prends de temps en temps. C’est confortable et surtout discret sous un pantalon jogging. Je recommande à toutes celles qui ne veulent pas avoir mal aux parties intimes durant ou après un vélo. Autre chose c’est léger donc parfait en été et en hiver.
J’ai acheté et essayer je suis très contente confortable

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
