    A true mummy cut for warmth

    This is a proper mummy bag, tapered to 210 x 80 x 50 cm so there is very little dead air for your body to warm. That close cut is what makes a mummy shape efficient: heat gathers around your core and feet instead of leaking into empty space. Inside, a white duck feather fill does the insulating, the kind of natural down that gives a lot of warmth for very little weight. A soft-touch 2D lining sits gently against your skin so the bag feels comfortable rather than clammy.

    Down warmth, in the weight you need

    The fill is offered across a wide range of weights, from 400 g up to 3000 g, so you can pick a lighter version for milder trips or a heavier loft for genuinely cold nights. The 400T nylon shell is breathable yet tough, resisting tears and shrugging off moisture, though as a water-resistant fabric it is not a bivvy replacement in steady rain. One point worth knowing: natural down loses loft when it gets wet, so keep it dry. Choose from Blue, Red, Green, Black or Orange.
