Down Insulation & Fabric Technology

650 Fill Power – Lightweight Natural Warmth

The Nova features 650 fill power duck down insulation, combining 90% duck down with 10% feathers. Fill power measures the loft of down insulation, indicating its ability to trap insulating air relative to its weight.

This helps the jacket deliver comfortable warmth in a lightweight, compressible design that's easy to pack and carry.

Water-Repellent Nylon Ripstop Outer

The 100% nylon ripstop outer fabric combines lightweight durability with a water-repellent finish rated at 1,000mm. It helps resist light rain and moisture while providing a protective outer layer during outdoor activities.

The Nova is water repellent rather than fully waterproof and is best paired with a waterproof shell in prolonged or heavy rain.

Compact Pack-Away Design

The Nova packs into a compact storage sack, making it convenient for travelling, hiking and days when temperatures change. Its compressible down filling allows the jacket to be carried easily in a backpack without taking up unnecessary space.

Fit & Styling

The Mac in a Sac Nova features a unisex regular fit, providing a comfortable shape for everyday wear and layering. The curved hem can be adjusted using the drawcord to improve fit and help keep cold air out.

Wear over a fleece or lightweight jumper for cooler outdoor adventures, or pair with jeans and trainers for casual everyday use.

Choose from four versatile colours: Fjorb Blue, Soft Orange, Slate Grey and Jet Black. As this is a unisex style, we recommend checking the manufacturer's size chart before ordering.
