Thanks, I actually won them on ebay for $80 but they retail for $345 according to the listing. The width is 4.25". They were tight on me when I first put them on, but since they have stretched out nicely and are really comfortable.
I believe I saw a Shopjake price tag on the box, so that's probably where they originally came from. No idea about an LL Bean collaboration, but it does say these were "handmade in Washington County, Maine."
