The Sierra Designs Nitro 0 Long combines a traditional mummy shape with 800-fill PFC-free DriDown insulation. Designed around a lightweight construction, it uses 15D nylon ripstop for both its shell and lining.
A draft collar and sidewall baffles help retain warmth and keep the down in position. The self-sealing foot vent offers a way to release excess heat, while an anti-snag zipper makes entry and exit easier.
The Long version fits sleepers up to 198cm and has a listed minimum weight of 1.23kg, including 820g of down. Twist Distribution gives EN comfort and limit ratings of -9°C and -17°C respectively.
