Re: CYA wool covers....
I got mine this weekend! Used it for the first time last night. It is generously sized, the small fit pretty well over our medium bionic VBSN . . . And it held up well, especially for as thin as it is!! It's soft enough that it doesn't bother my sensitive skin (I had to sell a few wool covers recently because they gave me a rash, just holding them long enough to put them on dd!)
