Vango Nitestar Alpha 250 Sleeping Bag

The Vango Nitestar Alpha 250 sleeping bag delivers proper three-season comfort for UK camping trips, DofE expeditions and festival weekends. Built around Alpha insulation - a 50/50 blend of polyester and siliconized hollow fibres - it traps air both between and within the fibres to maximise warmth whilst keeping pack size manageable. The offset construction technique layers the shell and lining stitching in different positions, which eliminates those cold spots you'd typically find along seam lines. Temperature ratings follow ISO 23537-1:2022 certification, meaning the numbers you see have been lab-tested rather than estimated. The mummy taper cuts unnecessary fabric from the foot end, improving thermal efficiency and reducing what you're carrying. Polair Hex fabric on the outside provides a 68D polyester shell that's tough enough for regular use, whilst the 190T brushed microfibre lining feels genuinely soft against skin. A 3D anatomically shaped hood with drawcord adjustment lets you seal in warmth on cold nights or loosen things off when temperatures rise. The insulated shoulder baffle works with the hood system to stop heat escaping from the neck area. You'll find an auto-lock two-way zip that won't slide open whilst you're asleep, plus zip guards with anti-catch piping and an insulated baffle running the full length to prevent heat loss. Internal storage keeps your phone or headtorch within reach, and hanging loops let you air the bag out properly between trips.

This sleeping bag appears on the Duke of Edinburgh's Award Recommended Kit list, which tells you it meets their criteria for reliability and value on multi-day expeditions. Young people completing their Bronze, Silver or Gold awards often choose it because it balances warmth, weight and budget sensibly. The siliconized coating on the hollow fibres does two jobs - it stops the insulation clumping together after compression and adds a degree of water repellence if condensation builds up inside your tent. Regular campers appreciate how the horizontal stitching keeps the fill evenly distributed, so you're not left with thick patches in some areas and thin spots in others. The woven zip pullers make operation straightforward even when your hands are cold, and the whole package compresses down enough to fit in a rucksack without dominating your pack space.

Whilst the Nitestar Alpha 250 handles spring through autumn camping confidently, you'll want additional layers or a warmer bag for proper winter conditions below freezing. The mummy shape works well for heat retention but some people prefer the extra shoulder room of a rectangular bag if they move around during sleep. Vango includes this model in their best-selling Nitestar Alpha range because it hits a practical middle ground - warm enough for cooler nights, light enough for backpacking, and priced reasonably for families buying multiple bags. The Polair fabric lining genuinely makes a difference to comfort compared to standard nylon linings, particularly if you're camping in just a t-shirt. Pack it in its compression sack between uses and the synthetic fill will bounce back reliably season after season.
