When keeping pack weight low is the priority, the Stoney Creek Black Stag Integrity 500 delivers the warmth and packability needed for summer and shoulder-season adventures. Built around 500g (17.6oz) of premium 90/10 down with 700 fill power, it provides efficient insulation while remaining light enough for fly-in trips, hut missions, and minimalist overnight setups.

The performance mummy shape helps retain warmth by reducing excess internal space, while the low-profile hood, twin collar, and full-length draft tubes work together to keep heat where it belongs. Trapezoid-shaped baffles and a blend of horizontal and vertical chamber construction help prevent down migration, maintaining consistent insulation throughout the bag.

Moisture can quickly reduce the effectiveness of untreated down. That is why the Integrity 500 uses DwrDown hydrophobic treatment, helping the insulation stay drier, loft faster, and continue performing when conditions are less than perfect.

Despite its warmth, the bag remains highly packable. The included water-resistant compression bag helps reduce bulk, making it easier to fit into lightweight pack systems where every litre counts.

A strong choice for warmer-weather expeditions where space and weight matter just as much as a comfortable night's sleep.
