Bueno, pero...

Es muy chulo, cómodo y ligero, quizás demasiado ligero. Me explico, me encanta, pero al primer enganchón con una rama se me ha hecho un buen siete en la manga. Precisamente lo que mejor caracteriza a la ropa para mtb de Decathlon es la durabilidad y aquí es donde falla. Pero vamos, nada que no arregle un buen parche de tela.

MUy transpirable y comodo

Maillot para uso de AM perfecto! cumple al 100€ para lo que esta echo! es muy transpirable u muy agradable al tacto!

très bon produit, mais…

très bon produit, mais le flocage ne correspond pas a l'image du site de vente (orange au lieu du vert fluo du AM 100 )

Additional Product Information


Main fabric

  • 82% Polyester cationic
  • 18% Spandex

A highly breathable jersey

To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092). The lower its resistance, the more the fabric will let water vapor produced by the body escape, and therefore the more breathable it is.

Designed for steering

This jersey has been designed to offer great freedom of movement. You won't notice it whether climbing or descending. Its close fit and the colors we have selected guarantee a pure all-mountain style.
