The Vango Cobra 900 Down Sleeping Bag, with its distinctive shape, is Vango's lightest weight, expedition-rated sleeping bag designed for demanding users exploring the world’s toughest environments. The high loft, low bulk design offers unparalleled warmth to weight with a tapered mummy shape that hugs your body to minimise heat loss.

Vango's 700 fill power goose down insulation is treated with our Hydro Barrier finish that keeps it drier 4x longer than untreated down. The durable 20D nylon shell fabric is also water resistant to keep the elements at bay and ensure consistent performance. Our unique Thermal Reverb aluminised layer reflects heat back to the user whilst the Welded Box Wall construction eliminates stitched seams, reducing heat loss.
