Platypus insulator hydration system ( EXCELLENT CONDITION ).
One of the only well thought out insulating sleeves out there. Used a handful of times on expeditions but in excellent condition. Fits a 2 litre platypus hydration bladder. Has handle at the back to make it easy to carry to and from water source. Tubing insulation thrown in for free as has a crease from storage but is in otherwise great condition.
