Jump to: Our Verdict / Features / Specifications

The Nemo Coda 10/20 Down Sleeping Bag exemplifies ultralight innovation and sustainability, making it a prime choice for serious backpackers. With its sleek, tapered mummy design, the Coda maximises efficiency by eliminating unnecessary material and weight while ensuring top-notch performance.

Nemo says: 

With NEMO’s signature quality and innovation, Coda represents a new vision of what ultralight sleeping bags can be. Inspired by the traditional tapered mummy bag, Coda has a sleek, streamlined silhouette that shaves excess material and weight wherever possible — but doesn’t stop there. A mono-polymer design, Coda also meets our Endless Promise™ standard and can be fully recycled at the end of its life.

Our Verdict

The Coda 10/20’s temperature ratings are impressive, with an ISO comfort rating of -7°C and an ISO limit of -12°C. These ratings make it suitable for cold-weather adventures, providing reliable warmth in temperatures that can dip well below freezing. The 800 FP RDS-certified down insulation, treated with a PFAS-free hydrophobic coating, ensures the bag remains warm and dry in various conditions.

One of the key features is the Headwall™ Draft Guard, an overlapping internal collar that offers comprehensive protection from drafts, creating a cosy sleeping environment. Additionally, the Thermo Gill™ Vent system allows for adjustable ventilation, enabling you to release excess body heat without exposing yourself to the cold air directly, making it versatile for different temperature ranges.

The bag’s construction reflects Nemo’s commitment to sustainability. It features bluesign® approved recycled materials for both the shell and lining and adheres to the Endless Promise™ standard for full recyclability. This eco-friendly approach doesn’t compromise the bag’s durability or performance, ensuring it stands up to the rigours of the outdoors.
