Long shot: light, compact ‘fitted sheet’ for couple’s joined mattresses?

In the mean time I stumbled across the Feathered Friends Penguin 'groundsheet' which is basically a pair of side-by-side pad sleeves topped with brushed polyester and bottomed with nylon that can mate with their Penguin rectangular sleeping bag. It looks like a cool system. The Penguin groundsheet is 13.5-14.2 oz depending on length. Not exactly minimalist, but looks pretty comfy. http://featheredfriends.com/penguin-groundsheet.html/

My wife and I have one of those and like it a lot. The fleece sheet is very comfortable and came in well under the published weight (sorry, I forget what I weighed it at). The only thing to be aware of is a small gap at the bottom of the bag, where the sleeping bag folds out. I think we put a bag there to keep out the breezes.

Nemo makes a stretch jersey ‘Slipcover 2P’ in 2×20″ and 2×25″ widths, very slightly cheaper than the FF model (and available through the usual ActiveJunky + sale places); very few specs available but Amazon lists a shipping weight of 11.2oz, slightly under list for the FF model, likely due to the lack of zippers.

Rep for quality wise I’d go with FF; also the FF version is flat black, whereas the Nemo is hideous. The danger with getting the FF groundsheet is the eventual irresistible need to get the Penguin or Condor to go along with it. ;)

We share a Feathered Friends Condor sleeping bag and groundsheet.  2 adults and a toddler.

Cascade Designs used to have them – may be available on-line still, currently only have this, although apparently it is connectable to other liners
