Review on 🎒 MIRACOL Hydration Pack Water Backpack: 2L Water Bladder Included - Insulated Hydration Backpack Bag for Men, Women, Kids - Ideal for Running, Biking, Cycling, Hiking, Festivals, MTB Riding by Pao Novakovic

I use it while skiing. This is primarily a water bag but I was able to wear my vest on the outer straps and I can always stash my phone, keys etc in the zipped pocket. I think it's good that the hose is insulated, but you have to drink often in very cold temperatures, otherwise the water in the hose freezes. I would recommend this backpack to all my friends.
