Review on Ultimate Hydration Solution: 2L Water Bladder Reservoir for Runners, Bikers, and Adventurers - Stay Hydrated on the Go! by Brandon Pratt

No problem with this product. It has all the features I was looking for. I took it hiking for a week and it held up well. I like the bite valve and ended up appreciating two sizes of bladder holes as it's easy to fill with the small hole and easy to clean with the big hole. I didn't notice any leaks when testing or using it. A volume of two liters is quite sufficient, but it is enough for a whole day of hiking; I think three liters makes more sense. I will also note that the one I received was production dated sometime in 2017 (I can't remember the exact date and I assume it is the production date too). It doesn't bother me too much, but it's worth noting that the product sat around for a couple of years before I received it.
