This pouch grips the HTC Desire quite tightly when the outside expansion section is zipped closed, but the phone is just slightly longer than the pouch. Another zip opens a pocket into which has been sewn a clear plastic holder for a couple of SIM cards. The inner holder pockets are too small for an SD memory card but would take a Micro SD card. A strong strap can be closed with a press popper round a waist belt. A separate band can be threaded through a loop on the pouch and fastened to your arm with velcro. A separate neck strap can be clipped to the pouch and the phone hangs half way down my chest (I'm 5 foot 3 inches). Everything is high quality but I'm still not convinced this product, or any other, will stop my phone from crashing to the ground and breaking. Seems as though you can have a holder that allows you to start using your phone within a second or two but doesn't provide great protection, or you can bury your phone deep in a rucksack or padded bag. Shame.
