Down Insulation & Fabric Technology

650 Fill Power – Lightweight Natural Warmth

The Nova uses 650 fill power duck down insulation, with a filling composition of 90% duck down and 10% feathers. Fill power measures the loft of down insulation, indicating how efficiently it can trap insulating air relative to its weight.

This helps the Nova deliver comfortable warmth in a lightweight, compressible construction that's easy to pack when not needed.

Water-Repellent Nylon Ripstop

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

The Nova is water repellent rather than fully waterproof. For prolonged or heavy rain, we recommend wearing a suitable waterproof shell over the jacket.

Compact Pack-Away Design

The Mac in a Sac Nova packs into its own compact storage sack, making it easy to carry in a backpack or travel bag. Its compressible down insulation makes it a practical extra layer when temperatures change throughout the day.

Fit & Styling

The Mac in a Sac Nova features a unisex regular fit, offering a comfortable silhouette for everyday wear and layering. Although featured in our women's collection, the manufacturer's sizing is unisex, so we recommend checking the size guide before ordering.

The adjustable curved hem helps create a more secure fit, while storm cuffs provide additional comfort in cooler conditions.

Pair with walking trousers and boots for outdoor adventures, or style with jeans and trainers for casual everyday wear. Choose Dusky Heathers for a soft, understated look, Atlantic Teal for a fresh outdoor colour, Alpine White for a clean neutral or Jet Black for classic versatility.
