What a great idea!
I actually just recently found the water bottle love of my life:
http://www.innate-gear.com/c8-atheltic-water-bottles/p23-vite-plus-v2-color/product_info.html I found this brand at REI stores and fell in love after I got one and started using it. Stainless steel, BPA free, dishwasher safe, clips to my jogging stroller (with a clip not sold with bottle), and water flow air valve. WOW! I even lost the valve for the lid, emailed the company with my plight, and the sent me several extra valves AT NO COST! I now have 3 of these water bottles!
But I'd buy a Cathe one too if it was a good brand!
