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

Bought for longer day trips. Tried it for the first time on a hike to Raven Point on a Fiery Gizzard hike. It was found to be comfortable to wear all day and my drink stayed cool for most of the hike. There was enough space in the backpack for a few snacks and other items for the hike. The 2-liter capacity was enough for a hot and humid 10-mile hike on relatively rugged trails. It has been found that the fluid bag is easy to clean and the storage hoses are easy to clean. The large opening allowed me to dry the inside to reduce the chance of mold growth.
