Cracking piece of kit for serious mountain marathoner. 400g top bag based on the BalloonBed. I have one for sale. Check out the website:

Used once, injury forces me out of competition for this season and probably next. Very few around. Will accept £160 including postage within UK.
Email best bet. Cheers,
