I have had good experiences with Decathlon products before so decided to try the under-shorts. Unfortunately none in store, I had to order online. I told Decathlon I was 36" inch waist (I am in fact 34") and they said I was size large. Product arrived and they are VERY snug, I am athletic and not a large build but these would only fit those with a stick insect type figure. So size up ! I also found there is a gripper on the legs, which I specifically asked about as I do not like them, again I was given bad information by Decathlon customer service. Advice; only buy Decathlon products in store where you can see and try on before buying and if out of stock, go elsewhere.
Good fit and style. Plenty of padding. To wear under mtb style shorts.
I've tried padded shorts and padded undershorts from other shops but these are the only ones that I find comfortable. My biggest problem with other makes is chafing at the groin/very top of the leg - these are sufficiently wide and padded to avoid that.
Bought for partner but returned. They looked great, fitted well/snug but he found them uncomfortable with the gel pad seating. I guess it’s something you get used to.
Never actually worn them as I used the size guide to order them and when they arrived it turns out the size guide was wrong and couldn't even get them on. However they do look really comfy.
Comfortable good fit, well made.
Padding helps so much!
Bought these to try out the B'Twin pad before deciding on which bib shorts to buy. Several hours in the saddle and (with a bit of chamois cream) no problems at all. May stick with these and unpadded tights for a while.
Well padded and good fit
Very comfortable and perfect for long rides which I wanted them for
Cumple con las expectativas
Adquirí esta badana como complemento del short ROCKRIDER AM 500. Es la badana más cómoda y nadie debería pensar en comprarse las anteriores. Yo añadiría algunas incluso más cómodas. A diferencia de los culottes que ya la traen, esta pieza es más ceñida, quizá demasiado en los muslos, dejando marca. Teniendo en cuenta que es una prenda interior para verano, yo haría la malla menos tupida para mejorar el intercambio térmico, es decir, hacerla más fresca.
Primero diré, que lo llevo sin las sujeciones de los botones. Y se sujeta bien. Hago uso de 2 a 3 horas, teniendo buena transpiración,buena adaptación y buena almohadilla. El único pero,son la sujeción de los botones,me resultaron imprecisas , poco fiables
Nada que envidiar a culottes que valen mas que el doble.
