I’m putting my Cirriform SW 1p up for sale reluctantly.  I have about 20 nights in this shelter, and I love it, but as I’m getting on in years I’ve decided to move to a side entry double-walled shelter.  This 1st generation Cirriform originally started out as a tarp, but I had Gen at YMG (who is an awesome guy) convert it to a single wall tent, using all no-seeum mesh.  I also had a cuben bathtub groundsheet made to order (which is included in the sale) which easily clips in to the tent and floats on top of the mesh (like the zpacks hexamid).  It can be left in or removed for separate use.  Both the Cirriform and the groundsheet are in great shape – – no rips, holes, zipper problems, etc.  The Cirriform weighs about 16 ozs and the groundsheet weighs about 4 ozs.  I’m asking $325, which includes shipping in the CONUS, and I prefer paypal FF or buyer adds 3% to cover the paypal fees.  I can email photos upon request.  Thanks.
