Your hydration game has never been on point like this – Source Military Convertube will transform almost any bottle to a kind of tactical hydration bladder.
Screw the Convertube on, and put your water bottle in your chest rig, battle belt, or a backpack side pouch. Set the drinking tube on your chest area or a backpack shoulder strap: now you have a no-fuss method of having a sip of water while on the move.
