If you don't want to take Woof up on his offer... (sorry Woof)
I have a standard Alpkit Hunka bivvy in black that I need to get rid of. I bought it off here but its too small for me. The previous owner said it had 1 nights use and it looks new to me. I've used it for 10 mins indoors...
I need to get an ex-army one that has a bit more room in it.
