    Buy it...Now!!

    Works as expected, Great.....

    Used two of them on Mt. Washington NH. Kept my water from freezing. Temps were at 15 F. Wind was blowing at about 19mph consistently. Gusting up to about 88mph. Wind chill temps were considerably colder. Fits a 32oz nalgene great. Had enough room to put a disposable handwarmer inside also. Just to give it extra protection from the temperatures... Fits wide mouth nalgene bottles well, it does not like the narrow mouth ones. They are about an inch taller then the wide mouth ones...I had one of these attached to my HMG prism pack waist belt for quick access, the other was inside the pack...Also had the HMG Versa on the other side of the waist belt, it provided quick access to food....And yes, I had the HMG shoulder pocket for my phone on the shoulder straps..

    Buy all their products, they work great....

    Nice!

    I wanted this kind of insulation that would hold a 1L bottle of Nalgene! To prevent freezing in snowy mountains!

    More than just for Nalgene bottles

    The Insulator is super high quality as all Hyperlite products tend to be. It will keep my water bottle insulated for winter trips. But it will also protect my 100-400 Canon lens during the rest of the year. Great product!
