Which models are you asking about?what bottles keep water cooler longer?
Studies have shown that in hot temps, athletes that consume chilled drinks perform better. than those consuming consuming the same type and quantity warm. Personally, I'm fine with room temp to warm drinks in general, but if competing every little bit helps.I am not really sure why folks need/want cold liquid in water-bottles. I think carrying liquid on rides is for thirst and a little electrolytes if ride is long. I don't really care about having cold drink, just thankful for liquid to replenish perspiration and sweat. Sometimes when you are hot and exercising, gulping down cold liquid can be irritating and cause cramps.
I think most long distance runners and extreme athletes prefer tepid fluids to avoid cramps and gastric irritation.
