These are my favorite type of water bottle covers. They adjust to fit most water bottles under 30oz. The tactile bottle cover looks good and stands up to rough use. I have used mine for 2 years and cover is still in very good condition. The covers are easy to use with added versatility because of the D-rings and carabiner clip. I am unable to attach most handles to my Contigo water bottles without this cover. Because of the D-rings on the cover, I now have this option. For the paracord handles, I cut the plastic ring that supposedly fits under the lid but does not on mine. Instead I used small Nearockle silicone cable ties (purchased at Amazon) to attach the paracord ring to each of the D-rings. The carabiner clip makes it easy to clip my water bottles to backpacks and my power wheelchair.The one thing I did find is that the straps to go around the bottles' middle constantly loosened. I switched those out with large Nearockle silicone cable ties, purchased at Amazon. I also added a silicone bottom to prevent my bottles from sliding off tables and counters.
