Review on 🚰 Improved Insulated Deuter Streamer Tube by Adam French

Still frozen. Maybe I'm just in heavier conditions. I was snowshoeing on Christmas Eve and my reservoir hose froze. Installed and went out on New Year's Eve, it was warmer but my pipe froze from mouthpiece to pouch just as quickly as my partner's unprotected pipe. The temperature in both cases is between 20 and 0 degrees Fahrenheit. Day #1, very cold and no isolator = frozen tube. Day #2, not so cold and insulator = frozen tube. I don't know what to say, in my case the isolator is enough. to cover the entire open tube and a few inches in my backpack (Deuter Pace 30). Nothing is displayed outside of the package. Not recommended if your climate is cold enough, just bring bottled water to be safe, don't believe it.
