Review on 🥶 Optimal Cooling FREEMOVE Hydration Pack Backpack - 5-Hour Cold Water Retention, 2L Hydration Bladder with Cooler Bag, Adjustable Fit, Multiple Pockets, 10L Capacity - Ideal for Hiking, Running, Cycling, MTB by Eric Surabhi

When I first opened the box I was impressed. There was a lot of space in the backpack. The bladder itself seemed well made and I also liked that it came with an insulating bag. The bladder tubing was also insulated. Apparently the backpack is made for keeping things cold. This is particularly important to me because it gets very hot and humid in summer. I ran with a backpack once and I'm happy to say it didn't feel bulky. The backpack stayed in place and didn't move much. Overall I'm impressed and only time will tell how long the backpack lasts. My only complaint is that the water had a plastic taste when first used, but that's easily remedied.
