EcoVessel Leak-Proof Reflecta Dual Top Lid

Lid/Strap for "Boulder" style bottles that will also fit the "Summit", "Boss", and "Perks", as well as the kids "Scouts" and "Frosts" to give you added value and versatility. If there is a date of 2014 or older on the bottom of your bottle, the tops may not fit. If you need this top as a replacement for a Boulder top, please check the photo to see if it looks like your current top.
The top measures 2 inches tall and 2.75 inches in diameter. The top and strap come as one piece and is sold as a unit. The first time you use this top, please screw down tightly, so it will form a tight seal.
