Our Verdict

The Pajak Core 550 is a premium down sleeping bag designed for cold-weather adventuring. With an impressive EN comfort rating of -3°C, it provides toasty warmth even when temperatures dip below freezing.

Utilising 700-fill power RDS-certified Polish white duck down, the Core 550 packs an excellent warmth-to-weight ratio. The down is lofty and efficient at trapping heat. Waterproof reinforcements at the hood and foot box help preserve insulation performance if moisture gets in.

Pajak paid close attention to details that maximise warmth, such as 3D zipper baffles, to prevent down migration and heat loss. The ergonomic hood cinches down to seal in precious heat.

While made for winter use, the Core 550 is versatile enough for three-season camping as well. On warmer nights, unzip the full-length side zipper to vent excess heat.

With its outstanding -3°C EN comfort rating from premium down, the Pajak Core 550 is an ultra-warm and lofty cold-weather sleeping bag. Intelligent design features ensure every ounce of down provides maximum insulation. It’s an incredibly capable and packable sleeping solution for winter camping or mountaineering in sub-freezing conditions.
