Definitely the largest lens cap I have ever seen so far & this honour goes to NiSi for providing this very useful lens cap with their S6 Filter Holder Kit.
It helps protect the NiSi Circular Polariser that also comes with the S6 Folder Holder Kit and if the CPL is not mounted it helps protect my Nikkor 14-24mm f/2.8G so all in a very useful addition to the kit especially when I like to use this setup hand-held.
Check out this short clip introducing the S6 Lens Cap:
