I used it for about 3 months. The shoulder straps were slightly frayed, so I repaired them (see photos 8, 9, and 10). There is noticeable dirt on the front (see photo 11). Made with Cordura nylon. A simple daypack. It has a rounded silhouette. This is a daypack for adults that adds a relaxed feel to your style. SE stands for Separate SE. As the name suggests, the design is easy to use with two compartments: the main compartment and the sub-compartment, and it has well-equipped inner pockets. This is the L size, which is the same size as the DAYPACK SE that was previously available. It's the L size of the SE, so it's the DAYPACK SEL. MATERIAL: CORDURA 1000d NYLON (NYLON100%) SIZE: H45cm W41cm D15+2.5cm Cordura is a durable material with 7 times the strength of nylon and is a registered trademark of Invista.
