Vango Nitestar Alpha 350 3 to 4 Season Sleeping Bag

Why Choose the Vango Nitestar Alpha 350 Sleeping Bag?

The Vango Nitestar Alpha 350 Sleeping Bag is built for campers and expedition users who need dependable warmth in cooler UK conditions. Designed as a high-performance 3–4 season mummy sleeping bag, it delivers enhanced insulation for spring, autumn and milder winter nights while remaining practical for rucksack based adventures.

With a strong warmth-to-weight ratio and excellent compressibility, the Nitestar Alpha 350 balances thermal performance with packability. Weighing 1.93kg, it is suitable for trekking, youth groups and Duke of Edinburgh Award expeditions where reliable warmth is essential.

The advanced Alpha insulation uses a blend of polyester and siliconised hollow fibres to trap more air and improve heat retention. The siliconised coating reduces fibre friction to help prevent clumping and improve water resistance in damp UK weather. Combined with offset construction, this reduces cold spots and supports consistent insulation coverage across the bag.

The thermally efficient mummy shape minimises excess air space, helping retain warmth on colder nights. An anatomically shaped 3D hood, insulated shoulder baffle and insulated zip baffle work together to seal in heat, while the Auto-Lock two-way zip allows adjustable ventilation when temperatures fluctuate.

Certified to ISO 23537-1:2022 temperature standards, with a comfort rating of -1°C and a limit of -7°C, this sleeping bag is well suited to cooler campsite conditions. Backed by a 2 year warranty, extendable to 3 years when registered, the Nitestar Alpha 350 offers reliable cold-weather performance for UK outdoor use.
