Jack Wolfskin Mountain Sunrise (2012)

While down is more efficient than synthetic insulation, it suffers more if it becomes damp (from condensation in a tent for example). To reduce the chances of moisture affecting the down, the Jack Wolfskin Mountain Sunrise has a waterproof shell at the toe and head, the two areas most likely to get wet when camping. This does increase the weight and price, but it’s also slightly warmer than the other bags here too – another reason why it is a little heavier and carries a higher price tag. The bag comes with a compression stuffsack for easier storage in a rucksack. The side zip works well thanks to a good anti-snag design, and there is a decent baffle inside to protect against cold spots. There is a particularly wide and well-insulated shoulder baffle to trap air inside the bag, and the hood is also well-designed. The Jack Wolfskin Mountain Sunrise is a great bag for when there is a high risk of dampness affecting the down.
