The RAB Neutrino 800 Regular is an expedition-grade down sleeping bag designed to keep you warm on cold-weather adventures. Its focus is on combining high-performance insulation with a shape and size that accommodate taller campers without unnecessary bulk.
Filled with 800FP RDS-certified European goose down treated with a fluorocarbon-free Nikwax hydrophobic finish, it maintains loft and warmth even in damp conditions. The Pertex® Quantum recycled nylon ripstop outer shell and recycled nylon lining strike a balance between durability, wind resistance and breathability. At 215 cm long and 102 cm wide, it’s sized for users up to around 185 cm tall, ensuring enough room to stretch out comfortably.
An 800 fill-power rating means the down traps more air for its weight, delivering efficient insulation without excessive bulk. The Responsible Down Standard certification guarantees ethical sourcing, and the fluorocarbon-free durable water repellent adds moisture resistance while reducing environmental impact.
