Super, je recommande vivement cette article, de bonne fabrication, j’en ai plusieurs et depuis des années, j’aime beaucoup cette marque

Produit vraiment top. Excellent matériau, sac à dos très spacieux et super confortable. Il a plein de poches, avec une housse de pluie fournie dans un compartiment dédié, une poche pour ordinateur portable et tablette. Le seul point négatif, c’est qu’avec tous ces zips, il fait pas mal de bruit quand il bouge kkkk. À part ça, le sac est top.

Un bon sac pour ceux qui ont besoin de transporter de plus gros volumes sans avoir à dépendre d’une valise. Le matériau est de bonne qualité et il semble être physiquement résistant.
