I've been looking for a smart water-resistant pocket for housing the batteries in my new LED light on the bicycle. This bag takes without problems in the large compartment on the left side 2 battery packs a 6xAA cells. The batteries are used instead of a hub dynamo to power my LED light. In addition, you can accommodate even further odds and ends. On the right side you still has a narrow subject in which I now my smartphone Samsung S2 a place for, so that it is safely stowed while driving. The size of today's smartphones fits unfortunately not well in the rear pockets of a cyclist jerseys. If you want to tracking his tour by GPS this works flawlessly even in your pocket.
The processing of the bag makes a solid impression. Therefore, it has a fairly high weight of over 200g. Very great the Velcro straps are with which it is attached to the frame. Which are adjustable in wide range and can even be removed. The bag has a tight fit to the frame, so that I have not even taken off when I transported my bike on the car on the highway.
Overall it met my expectations. Therefore, it has achieved full marks for me.
