I was looking for a bag for my Garmin Zumo 350, the not great plotting and also must take no accessories. I could find my way to the item description well with the technical data. It was certainly risky to order the bag, as the Zumo than outdoor Navi but is somewhat bulbous, but the risk was worth it, the bag fits "tightly", but not too tight. For "leaner" Navis three rubber straps are incorporated to the one inside, behind which you can "pinch" the Navi. Please note that these the Zumo 350 no sense, that would probably be after the third time there ... Simple "Loading" in the bag is sufficient. On the other inside is a small "safety net" for extra memory cards or other things. The zipper and the external impression of this case are absolutely fine and trustworthy. The moored at a small loop carabiner provides additional mounting options, if the device velvet bag not even come under the tank bag. I hope that the forthcoming regular use not prematurely pulls the material affected. However, even if, at this unbeatable price you may have to resort to a new model. Short initial conclusion: Sturdy bag that fits well for the Garmin Zumo 350 without adding large.
