As everyone else has stated this is a great bottle. No leaks, keeps water cooler for a little longer than non insulated version and the shut off capable bite valve works great. Only issue I have found with this version is its length. If you are using this as a bottle for your bike cage, be aware that it is longer than the lower capacity version. If you don't have a lot of clearance in the middle triangle of your bike than this bottle might not fit, or be tough to grab when riding. Otherwise you can't go wrong with this product.
