COULDN'T BE HAPPIER...!!!
Platypus makes a top of the line hydration bladder, with many great featuers
1: very durable
2: very easy to remove hose to refill
3: being clear makes it easy to see water level
4: light weight
5: cleans great
I've used a platypus on 3 Appalachian Trail thru-hikes without any problems.
I highly recommend this product..!!
