In reply to phil_91:I dont know if this would be of any interest to you as its single skin but I am selling the Flysheet /Outer for a Syl Hexpeak V4A.(Its the slightly bigger 2015 version.)
It works as a very spacious one person tent Uses one trekking pole set to 140cm (the full extension of most poles) Weighs 730 grams , Pack size is 30 x 12 cms (but squashes down to about the size of a rolled ultralight thermarest)
Ive replaced the pegs for proper MSR Groundhog pegs
Specs for it are on here

I sold the inner/nest as I found it far too claustrophobic to use and just using the outer alone gave much more livable space. It has only been used for one week but repelled some very big storms in that time without the slightest problem, seams have been sealed and its in perfect condition
Looking for £85 (which includes recorded post)
