I have several of these because I like the look, but Klean Kanteen 27oz is a limiting factor -- not a great water bottle in the heat.

Anyone else use King Cage Iris? I found that traditional plastic squeeze bike bottles all seem to get stuck and not fit well in this cage, because they're too big and not rigid enough to spread the cage like the metal Klean Kanteen. I've used a 16oz Nalgene bottle in the cage, which works pretty well, but it also isn't great for biking.

King Cage also recommends a 16oz insulated bottle for the Iris, I assume also Klean Kanteen, but the model I'm not sure I can pin down, if you know which they are referring to, please advise. I've also emailed them.

Thanks for any other bottle recommendations for the Iris cages.
