The Jack Wolfskin Sundowner is a comfortable down sleeping bag with excellent freedom of movement. Snuggle down in this bag & you can stay warm while watching the sun set, even when temperatures are down around zero: its comfort rated to 3°C. The fill itself consists of premium quality 90/10 duck down with a fill power of 700+ cuin & a thicker fill at those areas of the body that are most sensitive to the cold. Its ovoid shape & full zip around the foot section provide greater freedom of movement as well as extra ventilation options. This is the ideal choice for anyone who likes a warm & cosy bag, but prefers to have more room when sleeping.
