Pajak Core 950 - winter sleeping bag

Mietprodukt

Built for extreme conditions – the high-performance winter sleeping bag

When preparing for frosty nights in the wilderness, a reliable winter sleeping bag is your most important piece of equipment. The Pajak CORE 950 is designed precisely for this purpose: for expeditions in icy environments, for trekking tours at snowy altitudes, or for winter camping in sub-zero temperatures. This down sleeping bag has everything you need for warm nights in a tent, bivouac, or under the open sky – even when the thermometer plummets well into the double-digit sub-zero range.

Maximum insulation with high-quality down.

The heart of this winter sleeping bag is its 950g filling of high-quality, white Polish duck down with a fill power of 700 CUIN. This down is not only RDS-certified and therefore responsibly sourced, but also renowned for its excellent thermal performance. The sophisticated H-chamber construction ensures that the down remains evenly distributed, preventing cold spots. This reliably retains your body heat, even on long, icy nights.

Lightweight, compact yet robust

Despite its massive insulation, the Pajak CORE 950 packs down compactly. With a pack size of approximately 32 × 21 cm, it fits easily into your trekking backpack – ideal for alpine tours with changing campsites. The TORAY Airtastic SLF15 DWR outer fabric is exceptionally lightweight, water-repellent, and windproof. This keeps the down protected from moisture, while the soft micro nylon WR lining ensures a comfortable sleeping experience.

Temperature ranges according to the manufacturer

✅ T-Comf: -10 °C (Eddy's temperature recommendation for this model is -7 °C to -10 °C)
✅ Temperature limit: -18 °C (limit for experienced sleepers)
✅ T-Extreme: -39 °C (emergency range, not a comfort zone)

Note on temperature perception:
The temperature ratings are provided by the manufacturer and are standardized. In practice, however, they can vary – especially if you are exhausted, hungry, or wet. The quality of your sleeping mat also has a significant impact, as down compresses at the back and therefore provides less insulation. A good sleeping mat is therefore essential for a warm night.
