Review on RUPUMPACK 18L Insulated Hydration Backpack with 2.5L BPA Free Bladder - Lightweight Water Daypack for Hiking, Running, Cycling, Camping - Commuter Fit for Men, Women, Kids by Paul Dahl

I bought this backpack for a 3 week trip to Vietnam. I have used this as our day pack and will continue to do so throughout the trip. I was looking for a water bladder backpack and this was one of the few affordable and roomy options I found. I could fit in a backpack: a DSLR Cannon camera, an Instax camera, a pair of sunglasses with a case, a light sweater, 2 iPhones, 1.5 liters of water in a bottle, 2 cans of sunscreen, bug spray, a large lady's handbag and random souvenirs. To be honest I put the cameras in ziploc bags before storing them in a water bag but there were no leaks although it's better to be safe than sorry. The water stayed cold for 5 hours (!) at 100 degrees. Before we headed out, I collected a water bladder, filled it with baking soda and warm water, and let it sit overnight. After that, we didn't have any more problems with the "plastic" taste. If you have a hose connection leak, make sure it is fully tightened. Overall it was a very good purchase and I look forward to using it on future vacations and camping trips!
