The main parts of the bag are made of rugged 1050D nylon, which is ripstop, scratch-resistant, durable, and long-lasting! You can drink cool freshwater on your trek because the bladder compartment is thermally insulated. A reservoir with an external fill port and integrated refill handle is ideal for people who do not want to lug out their pools every time they need to be filled.

Straps and shoulder straps are adjustable for the shoulder, chest, and waist. TPU bladder is replaceable and FDA-approved.
