I finished the first bottle at the 1 hour mark and started the 2nd and it was ice cold, I was surprised. It seemed it had just melted. I highly recommend these bottles if you want to have cold water on very hot days w/o stops at local liquor stores. If I had freezed the water in the bottle the night before it probably would have melted half way by the 1st hour.
85 degrees is "the hot days of summer?" That is 4 AM in January here LOL....... I bought a pair of those and gave them away to someone after the 4th or 5th ride. However, I am glad they worked out for you!
