Lightweight three-season warmth with a compact packed size
Pajak says:
Core 350 is a lightweight down sleeping bag designed for warmer seasons – from spring through early autumn.
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.
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.
Our Verdict
The Core 350 uses 350g of 700FP Polish white duck down and has a 3°C comfort rating, which puts it firmly in three-season territory. At 688g for the Regular, I think it offers a good balance of warmth, weight, and packability.
The Z-baffle construction helps reduce cold spots, while the full-length zip gives you plenty of scope to vent on milder nights. I also like the extra moisture-resistant fabric around the hood and footbox, where contact with condensation is most likely.
