Comments about Nathan Nathan Triangle Hydration Waist Pak:

Used this at my first half-marathon. Very light, even with the bottle filled, not bulky, good angle. Pocket somewhat small, although I managed to squeeze into it 4 gu energy packets. Will use it again for sure!

The waist pack is great for running. The water bottle itself leaks a lot. Use a disposable water bottle instead. There's an elastic hook to keep it in place. I'm short, and because of diagonal design, it doesn't push into the small of my back, and also makes it easier to reach around and grab without losing stride. Good pockets for house key, etc.
