High visibility is so important to us at ORTLIEB because it is a matter of safety. Both the waterproof, polyurethane-coated Cordura fabric in neon yellow and the black fabric parts of this bag are densely interwoven with high-luminosity reflective yarn. This composition turns the entire bag into an eminently visible reflector when it is picked up in the headlights of passing cars. With its 20-liter payload, this versatile daypack is just the right size for work, school and play. The detachable zippered pocket on the inside offers plenty of space for keys and other small items. Added carrying comfort is ensured by the foam-padded back, carrying loop and ergonomic shoulder straps, breast strap and waist strap. The edge protectors at the bottom increase the daypack's resistance to wear and tear. The front is designed to permit the easy attachment of a bike helmet or an additional safety light. - Waterproof daypack with comfortable foam padding - PVC-free reflective fabric - Increased visibility when hit by headlights due to highly visible reflective fabric in fluo yellow or black - Ideal as school backpack or for walks - Fixing for optional rear light or helmet (not included) - Wide waist strap - Fast access and easy loading due to roll closure with Velcro - Protection around bottom corners on rear side prevents abrasion - Removable inner pocket for keys, change, mobile phone, can also be used as waist strap pocket - Takes A4 folders - Carrying handle - Optional accessories: cell phone holster for shoulder strap, Velcro extension strap - Note: In order to meet standard IP64 (6=dustproof, 4=protected against splash water coming from all directions) the roll closure must be rolled at least 3-4 times.
