  Product Description
The Vango Nitestar Alpha 300 Quad Sleeping Bag is a top choice in the UK outdoor market, trusted by campers, trekkers and Duke of Edinburgh’s Award participants alike. Featuring Vango’s innovative Alpha insulation, a high-performance blend of polyester and siliconized hollow fibres, it effectively traps air for impressive warmth with minimal bulk. The Polair Hex fabric shell combines durability with a soft, comfortable feel, while the offset layer construction, insulated shoulder baffle and zip baffle work together to maintain consistent warmth throughout the night.

Designed for superior sleeping comfort, the Quad shape provides generous room around the feet compared to traditional mummy-style bags, allowing for a more relaxed sleeping position. The 3D anatomical hood and adjustable drawcords on both the hood and shoulder baffle offer personalised temperature control as conditions vary. A two-way auto-lock zip with anti-snag piping ensures smooth operation, while the internal pocket keeps essentials like a phone or headtorch close to hand. Practical hanging loops make drying and airing effortless between adventures.

Tested and certified to ISO 23537-1:2022 standards, the Nitestar Alpha 300 Quad delivers reliable three-season performance, perfect for spring to autumn camping across the UK. Its synthetic insulation retains warmth even in damp conditions, making it dependable in variable weather. The brushed Polair microfibre lining feels soft and cosy from the moment you get in, and the even horizontal stitching ensures insulation stays perfectly distributed for lasting comfort. Compact, durable and comfortable, it’s a fantastic option for backpackers and outdoor enthusiasts seeking dependable warmth and versatility.

Vango Nitestar Alpha 300 Quad Sleeping Bag Features


  • Polair® Hex Fabric - A strong, durable yet soft touch 68D polyester shell fabric with an embossed hex grid finish.
  • Polair® Fabric Lining - A super soft and comfortable 190T brushed polyester microfibre lining that's incredibly warm and soft to touch
  • Alpha Insulation - A lightweight 50/50 blend of polyester and siliconised hollow fibres that trap more air between and within the fibres to increase warmth retention whilst retaining compressibility. A siliconised coating reduces friction to prevent insulation clumping and increases water repellence.
  • Offset Construction - A double layer design that offsets the shell and lining stitching to reduce cold spots and increase warmth retention.
  • Quad Shape - Square shaped footer provides added space for movement and a more comfortable nights sleep.
  • 3D Hood - Anatomically shaped to provide greater comfort and reduce heat loss. A convenient drawcord closure allows for flexible adjustment in varying temperatures.
  • Horizontal Stitching - Evenly spaced to hold insulation in place and ensure even distribution throughout
  • Insulated Shoulder Baffle - Helps retain heat within the sleeping bag. A convenient drawcord closure allows for flexible adjustment in varying temperatures.
  • Zip Guard with Anti-Catch Piping - Helps to prevent the zip from snagging on the lining, allowing easy opening and closing
  • Insulated Zip Baffle - Prevents heat from escaping along the zip, reducing cold spots within the sleeping bag.
  • Auto-Lock Two-Way Zip - Seals in warmth and provides adjustable ventilation. Auto-lock prevents the bag from opening during the night and can be accessed from inside the bag
  • Woven Zip Puller - Allows you to quickly and easily move the zip
  • Internal Pocket - Provides convenient storage for small items
  • Hanging Loops - Allows you to easily hang your bag for quick and easy drying

Frequently Asked Questions


What temperature rating does the Nitestar Alpha 300 Quad have?
The bag carries ISO 23537-1:2022 certification which provides lab-tested temperature ratings rather than estimates. The 300 model is designed for three-season use across the UK, handling spring through autumn camping trips and summer wild camping at various altitudes. The specific comfort, limit and extreme temperatures will be marked on the bag's label as per ISO standards. This certification means the ratings come from controlled testing rather than manufacturer estimates.
What makes the Quad shape different from standard sleeping bags?
The Quad shape features a square-shaped footer instead of the tapered mummy bag design. This provides additional space for your feet to move around during the night, reducing that trapped feeling common with narrow mummy bags. The rest of the bag maintains an efficient shape for warmth retention whilst the footer gives you proper room to shift positions without feeling restricted. This design suits people who find standard mummy bags too confining around the feet.
Why is this sleeping bag on the Duke of Edinburgh's Award recommended kit list?
The Nitestar Alpha 300 Quad meets the specific requirements for DofE expeditions because it provides reliable performance across the conditions participants typically encounter during bronze, silver and gold expeditions. The bag offers proper warmth retention through offset construction and insulated baffles, packs down to a manageable size for expedition rucksacks, and uses synthetic insulation which continues to insulate when damp. The ISO certification provides verified temperature ratings rather than estimates, which matters for safety on multi-day expeditions. The durability of the Polair Hex fabric stands up to rocky campsites and rough handling typical of youth expeditions.
What is Alpha insulation and how does it differ from standard synthetic fills?
Alpha insulation uses a 50/50 blend of standard polyester and siliconized hollow fibres. The hollow construction within the fibres creates air pockets that trap warmth more effectively than solid fibres. The siliconized coating serves two purposes - it reduces friction between fibres which prevents clumping and cold spots after repeated compression, and it increases water repellence so the insulation maintains performance in damp conditions. This combination gives you better warmth-to-weight ratio than basic synthetic fills whilst keeping the bag compressible for packing.
How do you properly store and care for the Nitestar Alpha 300 Quad?
Store the bag loose in a large breathable storage sack rather than keeping it compressed in the stuff sack. Prolonged compression damages the loft of synthetic insulation over time. The hanging loops let you air the bag after trips - hang it in a dry space to remove moisture and body oils. Wash the bag when needed using a front-loading washing machine on a gentle cycle with specialist sleeping bag cleaner or mild soap. Tumble dry on low heat or hang to dry completely before storage. The siliconized coating on the Alpha insulation handles washing better than untreated synthetic fills, but you still want to minimise washing frequency to extend the bag's lifespan.
What does offset construction mean and why does it matter?
Offset construction uses a double layer design where the stitching lines on the outer shell and inner lining don't align. Standard single-layer construction creates cold spots along every stitch line because the needle holes compress the insulation. By offsetting these stitch lines between two layers, the insulation in one layer covers the compressed areas of the other layer. This eliminates cold spots and significantly improves overall warmth retention without adding much weight. You'll notice the difference on cold nights when there are no cold lines running across your body.
Can you join two Nitestar Alpha 300 Quad bags together?
Vango sleeping bags can typically be zipped together if you have one left-hand zip and one right-hand zip version. Check which zip direction your bag has before purchasing a second one if you plan to create a double bag. The auto-lock zips need to be compatible, and you'll want to ensure both bags are the same model for the zips to align properly along their full length. Some warmth will be lost compared to using the bags individually because the joined area creates potential for heat escape.
What size stuff sack fits the Nitestar Alpha 300 Quad?
The bag comes with its own compression stuff sack sized appropriately for the packed dimensions. If you need a replacement or prefer a different compression sack, look for options around 8-10 litres for comfortable packing, or 6-8 litres if you want maximum compression. The synthetic Alpha insulation compresses reasonably well but won't pack as small as down. A compression sack with straps lets you reduce the packed size further, though over-compression repeatedly can eventually damage the loft of the insulation.
