Comments about Amphipod RunLite 4 Hydration Belt:

Two of the four water bottles leak. They dont leak enough that your shorts get wet. You can still use the water bottles for long runs (half marathons), but I will consider different products next time.

The flasks are secure if "clicked" in properly.

The belt was adjustable to all waist sizes (a newer version) the old version had an option to choose. This was a little confusing on the Campor web site

Bottles stay secure when attached correctly. The two-compartment mini 'fanny pack' attachment is good design: the inner compartment can be used to store goo packs and other nutrition/fuel. The outer compartment is best used for electronic devices, such as cell phones, which should be kept as far away as possible from sweating bodies. However, I still recommend placing such devices in a plastic bag and then place them in the outer compartment. For my first real-world use it was raining...and this fanny pack is not waterproof (not that it should be).
After a four-mile shake-down run and a 14-mile long run, the only draw back: one side of the belt is doubled-up as that is where the slack is stored as you adjust the size to fit your waist. Because the belt is at double-thickness on that side, the bottle racks do not move. On the other side, however, the bottle racks want to slide around--in my case they want to move forward as I run. Keeping the 'fanny pack' on that side and forward of the bottle racks does mitigate this movement somewhat. It may be just a case of further taking up slack to make the belt fit tighter. I still like the overall performance of this product.
The small hidden pocket at the velcro belt buckle is a nice touch...great place to hide your car key or car door lock remote.
