Elite

The spout gives you a full stream. The thin walls allow you to squeeze the bottle easily. The design of the cap allows for easy cleaning. It also allows you to get the last squeeze of fluid, leaving the bottle totally empty, unlike every other water bottle I've ever used.

Might just be a gimmick, but we are using this after every ride now. Looks like the bottles are cleaner than before. The Elite bottles also easily get deformed, and this gets them back to their proper shape.

Great bottles, love the higher capacity. They definitely have a faster / higher volume flow per squeeze which makes it much easier to grab a quick drink. I like the clear bottles so I can easily see how much I have in there. The caps can be a tiny bit leaky. A few drops here and there are irrelevant outside, but can add up during longer indoor rides. I'll certainly take light-weight over unnecessary extra weight, but the weight of the bottle is a pretty minor factor when you consider you'll have almost a whole kg of fluid in one.

Perfect water bottle. Cheap, easy to fill, and easy to squeeze water out
