Review on 🎒 Hydro Flask 20L Hydration Backpack - Variety of Sizes & Colors by Noe Miceli

I was extremely pleased to receive this backpack today as I wanted to test the water pouch and see if it really does hold cold water for 4+ hours. I quickly became disillusioned when I saw how dirty the water bag was. At the edge were black spots/spots. At first I thought it was mold. I started rubbing it with soapy water and warm water but it won't come off. I spent a lot of money on this backpack and hoped everything would look really good. I wonder if I can get a replacement. I think it's clean inside. Hope. Overall, the backpack makes a solid impression. Let's see how he behaves while cycling and hiking.
