Aunque aún no he probado la espaldera a simple vista se ve que es de buena calidad, es justo el complemento que necesitaba para mi chaqueta Vence Drystar.

Dorsal légère et bien aérée
Infante Mera Jonatan on 20/05/2021
No pesa nada y no se nota que la llevas, aunque es un coste extra sobre la chaqueta luego la puedes utilizar en otras chaquetas de la marca.
DIAZ VALDERRAMA Noe Francisco on 14/05/2021
Me da la sensación de que cumple perfectamente con el objetivo de protección de la columna.
Sanjorge García Melania on 25/11/2020
Me lo esperaba quizás algo más rígido, parece una espuma dura. Pero creo que cumple su función a la perfección, deja movilidad y protege
