EcoVesselBoulder Style 2-Piece Replacement Screw Cap for Newer Boulder, Bigfoot, Growler and Twist Bottles with Strap

I needed to replace the original one because it got dented. The top wouldn’t work properly and then I lost a piece from the second container the containers work excellently for my purposes, but they don’t keep things as hot as cold for longer period time as I had wanted but otherwise, and that for household purposes, the way I use it it works.

It fits my ecovessel triple insulated 64oz bottle, somebody said it won’t fit an older bottle. My bottle is very outdated it’s about three years old at least, perfect fit exactly like original. And I’m pretty sure it’s authentic!

Not the right cap for my bottle. I'm sure it's a fine replacement part, but not the right one. Looks right :-/ See pics. My Eco Vessel has a 1 7/8 inch opening, this one fits something like a 2 1/4 inch opening.

This worked great. I was happy I could buy a replacement top for our bottles. We use the eco vessels daily for fruit infused water.
