[GV Request] Bed Sheets

I'm assuming that there aren't any BIFL bedsheets, but I'm looking for something towards that end of the GV range. Something that is very high quality, very nice to sleep on, and will last as long as reasonably possible. Somewhat stain resistant would be nice - the last couple sets all ended up looking pretty dingy after just a couple months of regular use (including sexy-times and water-based lubes).

Suggestions?
