While I have not had this bottle on the golf course I did test it. The day I received it I filled it with ice and water. I then sat it out on my deck, it was about 3:30 and 91 degrees. That night it got to 74 degrees. Next day late in the afternoon, some 24 hours later, I opened it. The ice was gone but the water was still very chilled. It sat all day in the sun and several hours at over 85 degrees. Cannot beat that.
Pros:Nice sturdy well made bottle. Very well insulated indeed for the size. Easy to put ice cubes in and easy to drink from.
Cons:At 22 ounces it will not make a full round on a hot day.
