Nathan Nutrition Flask - 10oz

I bought this item as a replacement for a kid's lunchbox water bottle. It arrived promptly and was exactly as shown & described. The 3-pack was cheap and the quality of the bottles is excellent, better than my original bottle. With 3 of them, when the daycare loses another, I'll still have a spare. These bottles also fit the lunchbox better and the size of 10 oz. is exactly the same. Very happy with purchase.

I bought these to replace some worn out 11oz fuel belt bottles that I used in my standard Fuel Belt (trade name). The belt holds both 7oz and 11oz bottles in an elastic band. The nice thing about the Nathan bottles is that 1. they have a wide mouth for filling powdered mixes, etc, 2. they are sturdier than fuel belt bottles, and 3. the nipple stays open so you can drink without using your teeth to hold the nipple open.

I bought these extra flasks to go with my Nathan nutrition belt. They are an easy to manage size, and they fit well in the nutrition belt. The only problem with them is that they can be difficult to close if you are not careful.

Love Nathan's belt for long runs, as it secures nicely and has adequate storage. The water bottles do tend to leak out of the spout over time, requiring they be replaced. Also, cleaning the bottles and spout system is a bit of a chore. Overall, I prefer Nathan's system to others, but water bottles could be improved. I was unable to locate just the replacement water bottles at any sporting goods stores or speciality running stores in my area. I didn't want to replace whole belt, hence my reason for purchasing on-line.
