I handmade this pack with 1000d nylon fabric, 17337/55301 webbing, itw Nexus buckles and other milspec materials. This pack is based on the original molle ii patrol pack. I made this pack slightly taller than the original pack and added molle to the top for a general purpose pouch. This pack can hold a camelbak bladder in the pocket that makes contact with your back with a simple loop of webbing. There are some white markings visible, it’s is tailors chalk and can be brushed off. I oriented the side straps to be compatible with the FILBE Main Pack. Let me know if you have any questions.
