Robens Gully 300

The Robens Gully 300 is a two-season mummy-style sleeping bag made for spring and autumn camping, keeping you comfortable down to +9°C for women and +4°C for men.

Inside you’ll find 300 g of hybrid insulation that blends 50 percent RDS-certified duck down with MicroThermo Ball on the upper half, while the lower half is pure MicroThermo Ball. This mix balances warmth, compressibility and moisture resistance, and at just 0.9 kg it sits in Robens’ light category so it won’t weigh you down. The durable polyester shell stands up to regular use, and its 220 cm length accommodates taller campers without excess material getting in the way.

The down carries a 600 fill power rating, which measures how much air the down traps to boost warmth without adding bulk. RDS certification guarantees the duck down comes from farms adhering to responsible animal welfare standards. MicroThermo Ball is a synthetic insulation that mimics down’s loft structure and continues to insulate even when damp, helping the bag maintain its thermal performance in humid or changing conditions.
