My 2nd son needs a new anatote and I see now they make an insulating one, but I am not convinced this would be adequately effective. Plus I don't like the red color for a middle schooler trying to fit in. Has anyone tried it in hot and cold?
My oldest uses a Nike waist pack and we are very happy with that. He adds a frio in summer, though this is awkward because the one large enough to comfortably hold 2 epis is really too large. But my 2nd son wants anatote again.
Cannot comment on Anatote but the neoprene ones from KozyGo have always worked really well for most temperatures. And it comes in plain colours, including black.
