Great lid

Use it with my Hydrapak Stash 1L

By macneilpi

Not for Kleen Kanteen!

Fits my Nalgene but sadly it doesn’t fit the 40oz stainless Kleen Kanteen wide mouth.

prevents spilling

I love using the Watergate with my 1L Stash bottle. It helps prevent me from spilling water when I’m on the go – so it makes the wide mouth bottle opening more user-friendly.
