Coperchio di ricambio OctaLockTM Müv + Nav 15/25oz | Dark Aura

The OctaLock seal is noticeably snug on my Nav 25oz tumbler, so no leaks when I toss it in my bag. The Dark Aura color blends in nicely with the rest of my setup, and swapping it out took seconds.

The dark finish looks sleek against my 25oz tumbler, and the OctaLock seal keeps every sip from leaking during my commute. I’ve tested it upside down in my bag—not a drip, which is more than I can say for the last lid I owned.

The OctaLock lid snaps on so easily and stays sealed even when I toss my 25oz in my bag sideways. I love that it works with both my 15oz and the bigger one, so I’m not buying separate lids for each.
