Klean Kanteen Stainless Steel Water Bottles
We'd been looking for a nice modern stainless steel water bottle for ages and chose Klean Kanteen a number of years ago. Unlike plastic bottles, there is no funky plastic taste, the tops are non-leaching, and they will last a lifetime with care. Replacement tops are also available.
This classic, 18oz size is perfect to put on the underside of your downtube and can even fit in your backpocket!
The 18 and 27oz bottles are about 1-2mm narrower that many plastic bottles, so you might want to bend your bottle cage in just a touch for a perfect fit. The height for the 18oz is 8.75" and 11" for the 27 and 40oz versions.
Note: The 18oz and 27oz bottles feature a "sport top", while the 40oz bottle has a classic loop lid.
These are a great replacement for the plastic bottles I had which ended up being hard to clean. If you are bothered by a little noise though, I would not recommend it. It's not very loud but it is there.
