Review on RevX Thermal Hydration Backpack with 2L BPA Free Bladder - Keep Liquids Cool for Hours - Perfect for Hiking, OCR, Cycling, Camping, MTB by Richard Deng

I like that the liquid stays cold for hours. Florida summers are challenging. Lots of storage space so I only have to worry about 1 bag. Leaves hands free for paddleboarding and paddleboarding. I paddled down the Weekie Wachee River for 6 hours yesterday and it was still very cold. The only thing I have an issue with is how hard it is to drink from the mouthpiece, it's hard to take a bite. Might get easier with more use.
