Rab has long been one of the most tried and trusted manufacturers of down sleeping bags, and the Ascent 900 is its best value-for-money option. It features a temperature rating of -19 deg C, so it is warmer than all the lower- priced bags here, yet it still only weighs 1700g including the stuffsack. The bag is a little more spacious inside with a slightly squarer shape than other bags, to make it more attractive to first -time users and general winter campers who may find some closer-fitting bags too restrictive. To keep the weight down the 2012 version also uses Pertex Microlight on the outer and inner. The bag has a long side zip with a wide baffle as well as a wide shoulder baffle. The hood is easy to adjust and fits well. This is superb for those on a budget who also want a bag that is very warm, spacious and lightweight.
