The Hip Pack is my most popular size for men and women. I use this size myself when I travel; hands free and totally secure. It is a great alternative to a shoulder bag.
It measures 10x5-1/2x2-1/2, and the 52 inch fully adjustable webbing strap is secured with a top-quality Delrin side-squeeze buckle. The roomy main compartment is big enough for the essentials: wallet, keys, camera, etc.. I made a handy 7x4x3/4 zip cell phone pocket on the front, and a hidden back zip security pocket for the passport and big bills.
