The mummy shape gives you room where you need it and saves bulk where you don't, and also comes with a drawcord adjuster so you can burrow into the hood to save your head and shoulders from being exposed to the cold air overnight. Filled with lightweight synthetic fill and shielded by a ripstop outer, the Transition 300 will be a reliable companion on all your wild sleeping adventures. Anatomically designed to better fit the female shape, it has a wider fit through the hips and is shorter on the body to be more thermally efficient. Mummy-shaped bag with internal bungee adjustor cordWomen's specific designLightweight synthetic insulationNylon Ripstop outer3 seasonLeft-sided zipInner pocketSeason rating: 3Comfort rating: 2°CLimit rating: -4°CExtreme rating: -20°CDimensions: 200x75cmWeight: 1.93kg
