Perfect backpacking water bottle
A new must have for my backpacking gear. I use a CamelBak for my water but wanted something I could add electrolytes to and this is perfect. I don't go fully ultralight, but pretty light weight. This collapsible flask is perfect for a light weight water bottle that compacts down to almost nothing when it's empty. I've had it on 2 easy backpacking trips already totalling 10 nights. 2 more trips coming up to finish off the summer.Does not leak. No bad taste even the first time using it. So far it seems very durable and I'm sure I'll replace it if it ever wears out.Highly recommend.

Best 20oz Bottle on the Market
The manufacturer of this bottle makes a generic one that you can sometimes find for a few dollars cheaper - buy this instead, its worth the few extra dollars. It has a one click to lock the top which eliminates any leaking and is slightly thicker than any generic type, so it will hold up well.

Like much better than hard plastic handhelds
Bought this bottle to use in a hydration vest but carried it by hand one day. Wish I had bought the one with handheld unit so it’d be more versatile. Was difficult to keep in my hand for an extended period of time and it was too large to fit in pocket.

The bite cap is bigger now than previous models
The bite cap is wider now and a bit uncomfortable in my mouth compared to the previous Nathan Flasks of 2022 or 2023
