Great idea and it worked great. So nice to get a drink without having to remove the helmet and on the fly.
One problem, the description says angled bite valve but came with straight. Had to buy an angled valve so I could get it in my mouth with the full helmet on. (Posted on 8/1/12)
Nice idea. Mine did not come with the angle bit value as it say in the description. But I was provide one at addional cost. There are three cap that are provided, one fits a water bottle the other two I have not found any that they fit. The picture in their detailed images shows five, and all the caps have a one way value so the fluids do not spill. I only receive one one way value. The other caps that are show in the detail may be more useful. I wish I had one for a gatorade or power ade bottle.
