The Robens Serac 300 -4°C – Reliable Down Sleeping Bag for Cool Nights
The Robens Serac 300 is designed for outdoor enthusiasts seeking reliable warmth in cool conditions. Featuring 600 FP RDS-certified duck down, a comfortable mummy shape, and a compact packed size, it is ideal for trekking, cycling trips, and other adventures in temperatures down to -4°C.
Light, Warm, and Efficient
The 600 FP RDS-certified duck down (85/15) provides excellent warmth at minimal weight. The box-wall construction with insulated baffles reduces heat loss and keeps warmth exactly where it is needed.
Thoughtful Design for Cool Nights
An adjustable drawcord hood, improved collar, and shark-fin footbox reliably protect against drafts. The mummy shape allows mobility while the insulated face and neck baffles, as well as the continuous zipper baffle, minimize heat loss.
Comfort in Every Detail
The soft inner lining made of recycled polyester ensures a comfortable sleep climate. The sleeping bag features a YKK zipper with anti-snag protection, practical hanging loops, compression and storage sacks, and PFAS-free material tested according to EN 13537.
