Une pépite ce sac !

Dans la continuité des sacs de trail Responsiv, j'avais le 6L et je viens de prendre le 12L. Très confortable et ajustable avec les boucles. De nombreuses poches ultra pratiques. Même bien chargé, il se fait oublier ! J'adore !

Un super sac

C’est mon deuxième sac de trail et c’est toujours un plaisir, confortable résistant super bien pensé pour nous les filles, des poches partout, pratique, legé. Très fière de porter une marque française qui est aussi à l’écoute de ces traileurs sachant qu’on ne ménage pas le matos !! Merci à tous.

Sac d’hydratation responsiv 12L

Quelle belle acquisition. Enfin un sac qui répond à mes attentes pendant un trail. Le serrage avec le bouton micrométrique est idéal pour ajuster le maintien pendant la course. Ce sac contient assez de poches de rangement pour l’ensemble du matériel et alimentation.
