Saved us a lot of Time and stress. I purchased the 15 no rack Roof Bag (and the recommended rubber grippy mat to go under it) and Im very happy with it. I love the look of these and very comfortable except that the heel strap is just slightly too loose and its not really adjustable. While i?d LOVE to wear heels, my feet won?t let me do that and still keep a smile on my face. Powerbank is small and compact and looks good with the color. Als eine Hülle zum Schutz von Kratzern etc ist sie vollkommen ok. No need to worry about easy scratches. Sadly disappointed. I do weights, planks, jogging, etc. Bought it for my treadmill to watch videos as i workout.
