DiY Insulated Water Bottles (Winter Water Bottle Setup)

As an avid winter backpacker, I’ve delt with frozen water bottles way too many times to count. I’ve tried everything to prevent it. I’ve slept with the bottles in my sleeping bag, carried them in my jacket while hiking. Nothing really worked the way I was hoping it would.

So I started brain storming on ways to prevent my water bottles from freezing or at least put off the inevitable. After quiet a few trial and errors, I believe I’ve come up with the simplest way to keep my water bottles from freezing or at least not freezing as fast.

I typically care 2- 20 oz Gatorade bottles. I prefer these cause of the wide mouth on the bottles. I can pour my Skratch Labs hydration supplements, BCAA’s or Whey Protein in them pretty easy. I use 1 bottle to mix in and the other bottle I keep pure water in for cooking or simply just to have some nice clean water to drink. I’ve used this 2 bottle system for several years now and I don’t see my beardedself changing anytime soon.

So when I started experimenting with how I could keep my water bottles from freezing. I needed an item that could work with and fit around these bottles. I tried a series of different things like collapsible koozies, Neoprene, styrofoam, and so on..

Finally it hit me one day to try the old school, thick foam koozies. After a few hikes to field test it. I finally found what I was looking for. It worked! But I felt like there was still room for improvement. The cap was completely exposed to the elements which made it the weakest link in my new system. When carrying the bottle up right, water would freeze against the inside of the cap. Therefore either preventing me from opening the cap or once opened there would be a thick frozen layer of ice blocking my access to the liquid water inside my bottle.

Then out of the blue it hit me like a slap across the bearded face. The solution was to take a third thick foam koozie, cut it down till about 1-1/2″ (bottom part). Take this piece and place it in the bottom of the side pocket of the backpack. Making sure to place it with the koozie in the upright position naturally creating a foam cup in the bottom of my side pocket.

Once it’s in place, I put the modified bottle in the side pocket, in the upside down position so the cap of the bottle sits in the cut down koozie in the side pocket. By doing this the bottle is now completely enclosed in the foam.

Now I’ve been testing out this latest version and I have to say it’s been working out very well. To be honest, much better than I originally thought.

If you’re wanting to give this method a shot, you’ll need;

·3- Old School Think Foam Koozies (per each water bottle)

·1- 20 oz Gatorade or Powerade Bottle

These can be picked up at almost any store or online. As for putting it all together, just follow the instructions in the video. It only takes a few minutes to get each bottle set up.

So give it a try and tell me how it works for you..
