Review on Flex Sip Lid for Hydro Flask Wide Mouth Bottles by Brian Delgado

I can't stand sucking on straws so I was looking for the best cap option for my large hydro flask. It's a little sippycup-ish, but I like it. This is a good travel cap option so you don't have to open your big flap and pour water all over your shirt. Does not leak when properly installed. It only opens one way, and I'm always wrong, but when it's closed the mouth turns bright red, so if you look before you drink you'll be fine. My only complaint is that sometimes dirt gets stuck in the crease when I step on the floor, and sometimes my big nose blocks the vent and stops water flow.
