A three-season down mummy bag

This bag keeps things simple: white duck down inside a water-resistant nylon shell, in a mummy cut that pulls close around your body to hold heat and cut dead air. The 220 x 80 x 50 cm interior gives most builds room to settle without swimming in slack fabric, and a storage bag comes included for carrying it packed. Pick from two colours, Green or Blue, and two fill weights to match the season you camp in.

Choose your weight, read the rating honestly

The lighter 1700 g version carries a 10°C comfort rating with a -5°C limit, and the 2200 g version a 5°C comfort rating with a -10°C limit. Aim for the comfort figure as your working temperature, since category ratings tend to run optimistic, and add a liner for the last few degrees. Down carries the warmth, so keep it dry: the shell sheds dew, but untreated down loses loft once it soaks through.
