I've used Polar, Camelbak, and Elite insulated water bottles. The Elite Nanogelite is the best of the bunch IMO. Stays cold longer, contents taste cleaner, all without the unnecessarily complicated nozzles. YMMV.
Yeah, the Camelbak jet valve is so complex. Sometimes I have a really hard time getting a drink, and I have to stop and contact Camelbak for help.
