The Stoney Creek Blackstag 500 down sleeping bag keeps weight and packed bulk under control for hut stays and warmer outdoor trips. At 1kg (2.2lb), it is the lightest sleeping bag in the Blackstag range and compresses to 32cm x 19cm (12.6 x 7.5 inch), leaving more room for the rest of your gear.

Inside, 500g (17.6oz) of 90/10 down with 650 CUI loft provides the insulation. The listed -2C (28.4F) temperature rating gives you a clear reference point when planning where and when to use it, while the tapered rectangular shape gives you more room to settle in than a tightly cut mummy bag.

The central two-way YKK zip is a practical detail. It makes getting in and out straightforward and lets you open the bag for extra airflow when the hut or night stays mild. A single draft tube runs along the zip to help hold warmth inside, and the low-profile hood adds coverage without creating excessive bulk around your head.

Both outer layers use tightly woven, cire-treated 20D nylon to help contain the down fill. Once packed into the included waterproof, seam-sealed compression bag, the Blackstag 500 takes up just 9L (2.4 US gal). A strong choice when a lighter sleeping setup matters more than carrying insulation for colder conditions.
