Vango Nitestar Alpha 350 Sleeping Bag - Excalibur

The comfort rating is -1°C, while the extreme rating is -25°C.

It is rated for 3-4 seasons, meaning it is excellent for spring through late autumn; it is not designed for deep winter arctic conditions.

Store it loosely in a large mesh storage sack or hang it in a cool, dry place to prevent the insulation from permanently losing its loft.

The Polair fabric is durable and resistant to moisture, but the bag is not waterproof; always keep it inside a waterproof rucksack liner.

Please check the specific product label or your local distributor, as weight can vary slightly by batch, but it is designed for expedition-level portability.

Use the anti-catch guard intentionally by keeping one finger between the zip track and the liner fabric while pulling the zip slider.

Ensure you are using an insulated sleeping mat, as the ground absorbs body heat. Also, check that the shoulder baffle is tightened and the hood is adjusted.

Remove the bag from its compression sack and allow it to air out for several hours, shaking it periodically to help the fibers expand.
