10 Best Backpacking Sleeping Bags 2025 in the UK

The Vango Nitestar Alpha 350 Sleeping Bag is a solid choice for those venturing into 3-4 season backpacking trips, as indicated by its temperature rating. Its mummy shape is designed to enhance thermal efficiency by fitting snugly around the body, which could be very beneficial for retaining heat in cooler conditions. The sleeping bag features Alpha Insulation, which typically offers a good balance between warmth and weight, making it suitable for extended outdoor adventures.

Weighing in at 2 kg, the bag is relatively lightweight—important for backpackers who need to minimize pack weight. However, it may not be the lightest option available for those ultra-light enthusiasts.

The POLAIR HEX SHELL material is durable and breathable, adding a layer of reliability and comfort, while the POLAIR Lining ensures a soft feel against the skin, enhancing overnight comfort. There is a handy internal pocket for keeping small personal items close by, although the single size and maximum height recommendation of 182.88 cm might limit its suitability for taller individuals.

Vango's inclusion of a 3D hood with a drawcord closure helps prevent heat loss from the head, a feature that could be appreciated during chilly nights. Although the color options are various, the design may not appeal to everyone's aesthetic preferences. The sleeping bag is recommended by the Duke of Edinburgh award, which adds to its credibility as a reliable piece of gear for adventurous trips. For those embarking on backpacking expeditions within the specified temperature range, this sleeping bag presents a good blend of comfort, durability, and functionality, even if it's not the most compact or lightweight option on the market.

The waterproof outer shell and double-layer design enhance its durability and protection against cold and moisture, which is beneficial during unexpected weather changes.

The rectangular shape offers a comfortable fit, and the detachable double zipper system allows for customization of airflow, which can be adjusted according to seasonal needs. However, the shape may not be as heat-efficient as mummy-style sleeping bags, which is something to consider if you prioritize warmth. For comfort, it includes a camping pillow and a compression sack, making it easier to carry. It is user-friendly, with easy cleaning and machine-washable features, ensuring low maintenance. The vibrant color options and design appeal to a broad age range, making it a good choice for family camping trips.
