The most popular lid type, MontiiCo's Sipper Lid has been redesigned with new improvements and features as part of their Fusion range. Made to fit any of the MontiiCo Fusion base sizes, you can mix and match with your favourite base colour and size, for your very own personalised, made-for-you, insulated drink bottle. This lid comes complete with a straw to fit your 350mL MontiiCo Insulated Fusion Base (and can also be used with no straw if you prefer to tip ’n’ sip), as well as a matching carry strap to keep your hydration hero by your side. With a handy tab that allows you to open and close your sipper without touching the mouth piece, you can easily flip ’n’ sip one handed on the go! With a wider, upgraded mouthpiece, it's now a faster flow so you can sip in seconds.  And the best bit?! Say goodbye to dreaded spills - this lid is leakproof when closed tight. Note: MontiiCo's Sipper Lid + Straw 350mL will fit the MontiiCo Universal Insulated Base 350mL. Take a look here.
