Review on SHARKMOUTH FLYHIKER Hydration Backpack: Lightweight and Comfortable for Short Day Hikes, Day Trips, and Trails - Includes 2.5L BPA Free Water Bladder by Luis Adu

I bought this backpack for an 8 hour hike in 100 degree weather. I liked that there was a lot of water in the bladder and the mouthpiece was easy to drink. The insulated hose didn't keep the water warm, so I had to drink hot water until colder water came out of my bladder. I filled my bladder with ice in the morning to keep it decently cool, but by no means a cold afternoon. Next time I'll add a lot more ice and see if that helps. The backpack was quite comfortable to wear, so that's a plus. Once I put the hydration bladder in the backpack, it became difficult to fill the other compartments, so I wish it were designed so that other areas would be more convenient to use when the hydration bladder is full and in place. I'd still have a bottle of sunscreen, a hat, a small towel the size of a washcloth, extra duct tape to prevent blisters, sandwich bags of beef jerky, trail mix and banana chips, my small wallet, and my phone, so it all worked out.
