I made this assault pack with 500D nylon fabric, 17337/55301 webbing, itw nexus buckles and other milspec materials. This pack is dimensionally based on the Molle ii patrol pack. I made this pack taller than the usgi pack to allow space for a general purpose pouch. This pack is compatible with camelbak bladders. Let me know if you have any questions. I’m doing a sale right now, prices are reduced
