Sleeping Bag:  A bit of a dilemma - temperatures drop at night so I need a warm sleeping back, however, it needs to be a compromise between weight, warmth and bulk.  One of the warmest and lightest is the Marmot Atom; at less than 600g it is an incredible product.  However, lightweight comes at a price - around £165.  Synthetic materials are cheaper but almost fill the back pack.  Another one that looks like it will do the trick is the RAB AR Top Bag.  At 550g this is even 40g lighter than the Atom.  Any other suppliers who think they have the ideal product, please let me know.
