It is not an easy thing to find cycling water bottles that are made in USA. These are and they are insulated. I don’t think Polar Bottle makes a shorter version. I’d need a shorter bottle for my under the down tube bottle cage because a bottle this size would hit the fender or front wheel. Or I might just use that cage to carry my peanut butter.
I had one on my last tour and thought that the insulation was not the best but it did something. Although I was testing it in southern Texas, New Mexico and Arizona in July and August.
