Product Customer Reviews

The padded briefs can be separated and are really padded well. The shorts are sized well but the padded briefs are tight. I find everything at Decathlon are sized 1-2 sizes smaller than any other store in Canada. Quality is top notch. Store needs to maintain the racks better as everything is mixed up with makes it hard to find the right size

Chybí poutka na pásek
✅ sehr gute Qualität ✅ gute Passform ✅ Hose ist recht eng geschnitten daher eine Nummer größer kaufen ✅ guter Preis
Nach einem Jahr war der Reißverschluss defekt und die Hose war nach 2 Jahren nvon der Sonne sehr stark und ungleichmäßig ausgeblichen - sieht unschön aus.
Preis-Leistung ist Top
Ich trage normalerweise bei allen Rockrider-Produkten Größe L. Diese Hose war so klein, dass ich sie jedoch nicht einmal über meine Knie bekommen habe. Ansonsten machte die Hose einen guten Eindruck.
unglaublich wie klein diese hose ausfällt, beim "Vorgänger" Modell hatte ich XL, jetzt hab ich 3XL und die fällt noch kleiner aus als die XL vom Vorgänger... ansonsten hat Sie alles was ich brauch

Passt absolut nicht zur Größenangabe. Habe 2XL gekauft und fällt viel zu klein aus. Passt eher Menschen mit Größe L oder gar M.

Després de portar uns minuts el pantaló en temps calurós, la pell de les cames que ha estat en contacte amb un adhesiu que hi ha en el camal del culot pateix una erupció cutània que persisteix durant una dies. Comentant el fets amb altres usuaris, han coincidit en la mateixa queixa.

pantalon interno muy pequeño y aprieta demasiado
La espuma interior es una pasada. Y son muy comodos de llevar. La unica pega son los bolsillos, q no son comodos para llevar barritas o el mobil como asi lo indican.

Keep your gloves at hand
When mountain biking, gloves are often the last thing you put on and the first thing you take off. These shorts have a buckle on the waist so you can keep hold of your gloves without having to rummage around in your pockets. You can snap your ST100 and ST500 gloves on them using the press stud to keep them handy at all times.
