DESIGN
The Arsayo bag is a "city" backpack that can be worn with any style and in any season. Available in three sizes, the Arsayo bag fits any body shape.
Choose your size according to your shoulders .
COMFORT
The Arsayo bag feels like a jacket. Thanks to its wide, evenly spaced straps, the weight is perfectly distributed across your entire back. Its ergonomic shape will provide excellent comfort.
SECURITY
The zipper tabs fold down to the back of the bag to hold them in place with snaps. This makes it impossible to open the bag without the person feeling it on their back.
This unique system is patented and has been awarded the medal of the Ministry of the Interior and two Gold medals from the Lépine Competition (2016 and 2018).
