Where To Find 2" Topper Encasement?

I’d like to find a 2" topper encasement to make a topper out of a king size piece of latex I have. Preferably it would be made a breathable, cool material. Any advice on where I could find something like that? I’ve checked Amazon but to no avail. Maybe I’m using the wrong terms in my search?

Thanks!

Hi jaminjames,

The component post here includes the better sources I’m aware of for mattress and topper covers.
