They are guaranteed for life. I had 4 of them, but fell on one (between me and a motorcycle tipping over at 30 mph - 2 big dents in the bottle, but where the bottle hit my upper thy, I limped for 5 or 6 weeks.) Mine is called Contigo Autospout Sheffield Vacuum-Insulated Stainless Steel Water Bottle 20OZ
About 5 years ago, Costco had them a package of two for about $17 - NEVER AGAIN. They will replace parts, NO QUESTIONS ASKED. About once a year a check valve fails, and when you suck on the nipple, all you get is air.
They would not replace my dented one.
They will hold ice from 7 AM to 8 PM on days over 90 F. I generally carry 3. One on the handle bars and two in the trunk. They are great. You can drop them, and generally from waste level or a little higher, they won't even dent!
I believe this mount I use is a Kuryakyn. I've had it on there three years, and it is holding up well. No matter how rough the road is, the Contigo stainless steel bottle will not come out, and believe me, I've been on some very rough roads. I just completed Baltimore, MD to Fairbanks, Alaska and BC, MT, WY, ND & SD (and more than a dozen others) and the bottle never came loose. It is meant to go on both metric and imperial (US) bikes.
