Customer Reviews
Super produits, très pratique et stable avec le système BAO. Dommage que seul les flasques de la même taille que FUGA rentrent.
After an initial, somewhat uncertain outing, the second and subsequent uses convinced me. However, a few adjustments would still be needed to make it perfect. The designated pocket for the phone causes me pain near my lower ribs (I prefer to place it on my thigh instead), and the fit could be better adapted to accommodate breathing (the movement of the rib cage).
Great experience so far!
Très bon maintient, beaucoup de poche très bien placé ! Notamment la poche imperméable téléphone
