The way I found to personally carry my larger water bottle and Grayl kits. I made this specifically to carry grayl kits but will hold most water bottles. Straps around the outside of the bottles and attached to a shoulder strap with buckles. Also had shock cord to attach other items to the strap (think tump line) this set up will easily carry my Grayl kit, light weight hoodie and shemagh.
