Hybrid Down & EulinFiber

Details:

Hybrid Insulation System for Balanced Warmth:
Unlike standard synthetic or full-down bags, the Polar uses a hybrid insulation design:

High-quality duck down insulation in the upper layer for superior loft and warmth

Proprietary synthetic fiber insulation in the lower layer for moisture resistance and durability

This combination optimizes warmth, compression, and performance in damp conditions — making it ideal for unpredictable outdoor environments.

Technical Mummy Design for Maximum Efficiency:
The mummy shape reduces internal air space to retain body heat efficiently. An insulated warm collar with an adjustable concealed drawcord blocks cold drafts.

The shaped foot box enhances warmth while allowing natural foot positioning.

Loose-cover construction helps eliminate cold spots for consistent thermal performance.
