Perfect in my Nalgene!! I prefer drinking from a straw but im overly attached to my Nalgene and this solves it all.

Incredible value. Dropped into my 1L Nalgene with a tiny snip. It’s nice that it can easily be removed if you want it out, but it will stay put well if you leave it in. Great design 👌

Perfect for Nalgene

Exactly what I wanted - a simple, hygienic straw for my standard wide mouth Nalgene bottle. Clip the straws to size, insert. Just works!
