For those not fond of hydration packs, the good old canteen or flask works perfectly well and a pouch likes this makes carrying it that much easier. Of course, rather then just one or the other, you can combine both a hydration pack for water and a flask for something a little more interesting. After all, Airsoft is your down time so a wargame themed drink with the lads is not off the menu.
It attaches via a couple of Molle straps on the back. The lid is clipped down with a buckle, elasticized drawstrings can bind the top tighter and a couple of Velcro small pockets on the front are handy for little odds and ends.
Made of 1000D Cordura, the material is light weight but incredibly robust. With ITW Nexus buckle, milspec stitching and Velcro good for over 2,000 uses, it meets the harsh standards of military grade combat gear. This model is available in different colors.
