When you’re out on your bike in the city after dark, you need to make sure you stay visible. Carry the SPARKSLING, and you won’t have to worry. With LED illumination by OSRAM, this pack really stands out in the dark.To activate the LEDs, simply connect a power bank to the USB plug inside the pack. The illumination will work for at least nine hours. The main compartment of the bag has enough room for essentials, and small items can be stowed in the two large stash pouches.You can carry the SPARKSLING over your right or left shoulder – it’s super comfortable either way. Access to the compartments is good from both sides, and thanks to its innovative 3-point strap attachment system, the bag doesn’t swing around when you’re riding your bike or running for the train.
