The Neutrino 400 Extra Long Wide by RAB is a three-season down sleeping bag designed for campers who need a bit more length and width without adding bulk. Its mummy shape keeps you snug when temperatures dip toward freezing, and the extra room in the shoulders and hips makes it easier to shift around or layer up inside.
Inside, 400 grams of 800-fill-power, RDS-certified European goose down traps warmth efficiently while staying highly compressible for packing light. The shell is made from 20-denier Pertex® Quantum recycled nylon ripstop treated with a fluorocarbon-free durable water-repellent finish, so it sheds light moisture and stands up to abrasion. A soft 15-denier nylon lining adds comfort against the skin without weighing you down.
The 800-fill-power rating refers to how much loft each ounce of down provides, meaning this bag achieves a strong warmth-to-weight ratio. RDS certification ensures the down comes from responsibly raised geese, and the DWR treatment prevents dampness from reducing insulating performance. All of this combines to give a lightweight, durable bag that keeps you warm through spring, summer and autumn adventures.
