Review on Water Bottle Running Belt - Waist Pack with Water Resistant Pouch for iPhone, Samsung, 🏃 Android - Adjustable Belt, 10oz Bottles - Ideal for Running, Hiking, Cycling, with Race Number Attachment by Christopher Bates

A week before the Chicago Marathon I found out Camelbak water bottles weren't allowed - I bought this product in a panic! I only had 1 test run before completing 26.2 miles. With the bottles in the back it bounces too much but with the bottles in the front it stayed where I put it. No bouncing, no slipping (with 2 hours of continuous rain), no chafing; Bottles fit comfortably in bags. 20 ounces (total) isn't a lot, but I only needed it for my electrolyte and calorie mix - I didn't want to carry a lot of weight. Bonus: The middle pocket fits 3 gels and my iPhone 7 Plus so my friends can track my real-time mileage. Solid product - I'm a fan.
