Are you looking for alternatives to plastic water bottles after reading some of the albeit conflicting reports regarding Lexan bottles? I looked around a little and found these alternatives yesterday:
Klean Kanteen, a stainless steel bottle in 27 oz and 40 oz sizes.
Brunton Beverage Flasks, made from aluminum that has been covered with food-grade epoxy on the inside. Sizes range from 0.4L to 1.0L.
