Platypus Drink Tube and Bite Valve Insulator

2018-12-18T19:00:00

The drink tube insulator works great. The bite valve cover is a bit of a disappointment since it won't stay closed, generally popping open after just a few minutes of hiking. This results in freezing at the bite valve despite blowing air back into the tube, plus prevents the secondary usage of keeping the bite valve clean. Worthwhile purchase for the tube insulator, but I'll be looking for a better bite valve cover.

I've seen some reviews that state that the hose does not insulate, apparently they dont know that you have to pour warm water for it not to freeze, I used it on 5,250 meters above sea level at - 18 ºC and it worked just fine, only the water in the bite valve froze but as soon as it was in contact with the warm water ther was no problem at all I used it for 7 hours and it never froze, it only got cold
