Let me introduce you to the Gizeh Bag.
 
A bag:
Triangular in shape with grommets to allow cross-carry.
A double welt pocket hidden under the flap for the phone.
A zipped pocket on the back of the bag.
A large flap that follows the triangular shape of the bag and closes on the front with a turn lock.
Inside the bag, there are optional card holder and/or a removable key ring for easy access.
 
The originality of this bag comes from its shape which can remind us of an American holster ...
