Comments: The strap always loosens on my runs. Otherwise, works well.

Comments: Works exceptionally well! Bite valve is much more convenient than similar Nathan models. The Nathan bottle tend to pinch your lips. This one won't. It also does a nice job of insulating the beverage. My only commplaint is that the strap sometimes loosens while I run, but that could be operator error on my part.
I highly recommend this versus other similar models from other manufacturers.
