Pros & cons

• ISO comfort -5 °C for 1070 g: about 280 g lighter than Rab's Ascent -12 °C with the same rating
• 800 FP hydrophobic down and a Pertex Quantum shell suit damp, cold UK winter nights
• UOG: 'a slightly more forgiving cut than ultralight options', so it suits side sleepers
• At £570 RRP it costs well over the Ascent -12 °C's £360 for the same ISO rating
• 10D top fabric needs more care around crampons, stoves and rough bothy floors than 20D bags
