The bag is lightweight and provides both vertical and horizontal mounting options. That means sometimes I have it on your belt, then back to the backpack, also bicycle handlebar works. The light weight of the bag is just pleasant on long walks. If you have a compact camera usually fit even spare battery and Memory with pure.
Whether they actually withstand a rain, I do not know. But it is handy, lightweight and good protection. Falling from some meters have so far spotted my little cameras. Not that I would have created it ...
Those looking for a solid, well-made and versatile protective pouch for compact camera or the like, can find something at a reasonable price here. If you want a definitely waterproof (more than splashing) solution, but should probably look for something more!
