More about Robens Scoria UL +6°C

The insulation consists of 850+ fill power RDS-certified duck down (90/10), which provides a very high warmth-to-weight ratio. The combination of H-box construction and differential cut maximizes loft and ensures that heat stays where it is needed - without unnecessary weight. The design is anatomically optimized with a comfortable mummy shape that balances freedom of movement and heat retention. The 3D shaped hood, overstuffed drawcord and insulated 'shark fin' footbox minimize heat loss and protect against drafts, even on cooler nights. Material choices are consistently premium: an ultra-lightweight 10D ripstop fabric provides low weight and high packability, while the inner lining wicks away moisture for better comfort. The insulated zipper with anti-snag protection and YKK zipper ensure smooth and reliable use in the field. Scoria UL +6°C is thus a clear choice for users who want maximum performance in a minimal format - perfect for summer, late spring and early fall.
