Great bottle, fits most filtering systems. 28mm thread. Very easy to clean from the wide side. Exceptionally sturdy. The wide opening works perfectly for filling with water. You can turn it into a camelbak if you want—just mount your filter system on a tube to the mouthpiece. If the bottle is used for dirty water, it can also be used for washing clothes in the field when you're short on water. Pour water inside a sock and shake the bottle—refreshing done. :-) It's professional-grade equipment and very durable. Rinsing with baking soda eliminated the factory smell and it doesn’t absorb odors itself. There are also versions with 42mm threads, but you'll need adapters for filters then. Highly recommend.
