Commercially I have tried many pockets, but am unfortunately not found anything, too big, too small, too wide, too narrow, too pop to stuffy, just nothing that was tailored to the users and especially the camera. From the internet I can send 2 different products, both did not fit! With this bag, the TZ10, the replacement card and the spare battery is removed dead right. The bag is well padded, so that the content is well secured in an eventual "crash". Battery and daughter card are in good hands, and when the pocket (or yourself) is not upside down, nothing falls out! Price / performance ratio is fully in order. It is not a skin-tight "cloak", so anything that you can put in your pocket, but with the sturdy belt loop or the strap does this bag through "thick and thin". I am thrilled.
