Vango Nitestar Alpha 350 Sleeping Bag

The Vango Nitestar Alpha 350 Sleeping Bag is a 3–4 season synthetic mummy sleeping bag for camping and expedition trips. Its tapered shape, double-layer construction and insulated shoulder and zip baffles help retain warmth, while a soft, slightly brushed polyester lining makes settling down after a day outdoors more comfortable.

With a listed suggested usage range of -2°C to 18°C and a maximum user height of 190cm, it offers clear sizing and temperature guidance for planning your next UK camping trip. Choose your sleeping bag to suit the forecast, your sleeping mat and how warmly you sleep, rather than relying on its season label alone.
