I bought this bag new in 2009 to take to Everest Base Camp for use at BC while I was staying there. It performed fantastically, keeping me very cosy at extremely low temperatures and is one of the best cold weather bags I have used.
The down is extremely well packed and the bag is constructed to a high standard. The bag has been sitting at home since that 2009 trip awaiting another outing but as I have not got any further use out of it I have decided to sell it. I have been using a synthetic ME Lamina 0 for my Scottish winter outings which have been my only cold weather trips rather than the North Face bag.
The current model retails for £830 and I bought this bag for £799. As the bag has just been professionally cleaned and repacked and has only had 4 weeks use I think a price of £325 is reasonable. I do not have the Mountaineering Designs receipt to hand but I can source copy from them if required.
P&P anywhere in UK for £15
The only think I would note is I do not have the stuff sack for the sleeping bag as somewhere between it being stored unpacked and now it has been lost so it will arrive boxed and unstuffed without it.
