Müv + Nav OctaLock™ Replacement Lid 15/25oz | Matte Black

The OctaLock seal is a lifesaver—no leaks even when I toss my tumbler sideways in my bag. The matte black finish matches my original lid perfectly, so it looks like nothing ever happened. Fits snug on my 25oz, that's all I needed.

Lost my original lid on a camping trip, and this OctaLock replacement fits my 25oz tumbler perfectly. The matte black finish looks just as sleek as the original, and the twist-lock seal feels solid when I toss it in my bag.

The matte black finish matches my tumbler perfectly, and the OctaLock seal keeps every drop from leaking in my bag. I've dropped it a few times and the lid has stayed tight, which is exactly what I needed from a replacement.
