Review on 💦 EVERNEW Water Carry System, 2000ml: Efficient Hydration Solution for Outdoor Enthusiasts by Bob Larson

I use them as backup water. Lighter than a Nalgen bottle, takes up less space and is easier to pour. I have a screw cap so it doesn't open in my packaging. It has the same thread size as a 2 liter soda bottle. This allows the water filter to be easily screwed on with the swirl adapter. I used a regular stationery hole punch on the bottom (there are markings on the plastic for you to follow). I put a carabiner in the hole and attach it to my backpack when I need to refill my water bladder. You can fill it up halfway and put it in the freezer overnight. Filled with water at 5 a.m. It stayed cold and also cooled my water bladder. At 2:00 p.m., small pieces of ice were still inside. rolls well You can take an empty one with you as a reserve on a long hike or as a dirty water carrier. Filter it into a clean bottle and roll up the dirty bottle until you need it again. Just be sure to mark it so as not to contaminate clean water.
