Slugwash, i would be interested to hear how you got on with your sleeping bag this weekend.
Surfer , i have gone from a wee airic to ballon bed and extenisive living room testing has shown it to be fairly robust ,i burst a few ballons setting it up but none once in the cover, which is pretty well made i might add. In terms of weight saving and price compared to a neo air its a winer.
Saying that i havent usd it in anger yet
