Le compagnon ideal

"Ce sac est sublime, j’adore son design avec les cœurs. Il est très pratique pour les run de 1 à 25km. Il y a plusieurs poches pour mettre 2 flasques et/ou une poche 2l, sa veste de pluie, téléphone, clé, … Après plusieurs commandes pour essayer de trouver la bonne taille, il ne faut pas vous fier à la taille indiquée par le site, prendre 1 taille en dessous."
