This is version 2 of my hydro flask funnel.

It'll fit any flask that has a 53.5mm mouth inner diameter (Hydro Flask, Takeya) This funnel should work on any size (volume) flask.

Why?
Water flask does not fit under the ice maker. Would throw ice everywhere.

What are the improvements on vesrsion 2?
Old version was threaded which was cumbersome. New version fits inside and provides a better seal.
Ice would jam in the old version and ice would pile up in funnel. New design does not jam with ice.

Aloha! : )
