Core 350 is a lightweight down sleeping bag designed for warmer seasons – from spring through early autumn.
- T-comfort: 3°C
- T-limit: -2°C
- T-extreme: -18°C
Construction: Z-chamber design – ensures even down distribution and eliminates thermal bridges.
The areas most vulnerable to contact with condensation (the footbox and head sections) have been further protected with a high-moisture-resistance fabric. This solution prevents the down from getting damp, extending the sleeping bag's lifespan in rugged outdoor conditions.
Who is the Core 350 for
- Trips from late spring to early autumn.
- Camping in forests, mountains, and by the water.
- Mountain huts and overnight stays on the go.
- Ultralight packing when pack weight and volume are critical.
To maintain thermal performance, wash the sleeping bag using mild detergents specifically designed for down. Dry in a tumble dryer or in a well-ventilated area. Store in the large storage bag provided or hang it up to avoid losing the fill's loft.
The Core 350 excels on the trail, in the mountains, under a tarp, or in a tent. It is the perfect choice wherever low weight, compact size, and effective protection against the cold are a priority.
We have filled it with 350 grams of 700 CUIN Polish duck down. The down is distributed in Z-chamber construction to minimize the risk of cold spots and ensure the gear serves you reliably for many seasons.
