NEW!!! At last a way to carry more water. Klean Kanteen has just introduced their new 64 oz (half gallon) widemouth stainless steel water bottle. It comes with a Stainless Loop Cap that clips onto a Kanteen™ S-Biner. The cap is 100% stainless steel on the inside, so your drinks never touch plastic. In fact, the only plastic on the Klean Kanteen™ Wide is on the outside of the cap; and of course it's BPA-free polypropylene (pp#5). Great for travel and long work days. A great replacement for all those plastic water jugs! The extra wide opening is more than 2 inches in diameter for quick filling, pouring and cleaning, and the universal thread design fits with standard backcountry water filters.
