Vango Nitestar Alpha 250 2 Season Sleeping Bag Neptune

Why Choose the Vango Nitestar Alpha 250 Sleeping Bag?

The Vango Nitestar Alpha 250 Sleeping Bag is a lightweight, compact and thermally efficient 3 season mummy sleeping bag designed for UK camping, backpacking and expedition use. With an impressive warmth-to-weight ratio and excellent compressibility, it delivers dependable comfort without adding unnecessary bulk to your kit.

Weighing just 1.6kg, it is well suited to trekking, hiking and youth expedition groups, including those completing Duke of Edinburgh Award expeditions. The tapered mummy shape reduces excess air space to improve thermal efficiency while keeping packed size manageable for rucksacks and campsite storage.

The advanced Alpha insulation blend traps more air between fibres to increase warmth retention while maintaining loft. A siliconised coating helps reduce fibre friction to prevent clumping and improve water resistance in damp conditions. Combined with offset construction, this reduces cold spots and supports consistent warmth across the bag.

For cooler nights, the 3D adjustable hood, insulated shoulder baffle and insulated zip baffle help seal in heat. When temperatures rise, the Auto-Lock two-way zip allows controlled ventilation and secure closure throughout the night. Certified to ISO 23537-1:2022 temperature standards and backed by a 2 year warranty, extendable to 3 years when registered, the Nitestar Alpha 250 is a reliable choice for spring to autumn adventures across the UK.
