Sustainable Synthetic Insulation
All the ups without the down...
Since our founding, we’ve been committed to making down-free insulated jackets, using only synthetic fills. Dealing with down can be difficult, with live plucking common and sourcing chains hard to verify. Synthetic fills also perform better in a variety of conditions, retaining 75% of their warmth when wet compared to only 15% with down insulation. This ensures you're prepared to face anything the coastal climate can throw at you.

NEW for 2023 | REPREVE® Recycled Insulation
CONNECTING YOU TO THE SEA, KEEPING PLASTIC OUT OF IT.
2023 will see the introduction of insulated jackets containing REPREVE Our Ocean, a 100% recycled synthetic fill made of ocean-bound plastics. Keeping plastic out of the sea, and you warm in all conditions. By 2024, all our insulated jackets will contain REPREVE fill.
Offering superior high-loft insulation which outperforms down in wet coastal conditions, Repreve considerably reduces emissions as well as water and energy consumption in comparison to the production of virgin polyester; balancing warmth, performance and sustainability.
REPREVE® Our Ocean product is made 100% bottles collected from within 50 Km of coastlines in countries or areas that lack formal waste or recycling systems and infrastructure. There is no addition of virgin yarn or pre or post-consumer content, so 100% from bottles at high risk of entering the oceans and seas.

What is Finisterre Engineered Insulation?
In 2017, after nearly a decade of research and development, we introduced Finisterre Engineered Insulation (FEI); our own synthetic insulated fill that had a higher recycled content than anything that was available on the market. But we didn't stop there. We then created our A-form insulation made from 100% recycled polyester; offering the same high-loft as down, but with increased performance in wet conditions and less impact on the planet. These innovations have served us well but from 2023 we be transitioning to use REPREVE® Recycled Insulation in all our insulation.
The perfect blend of warmth, performance and sustainability.
FEI A-form
Named after the Altocumulus cloud type - this synthetic fill replaces our C-form insulation, closely mimicking the high loft aesthetic of down but with improved performance and considerably less environmental impact.
- 100% recycled polyester content
- Superior warmth to weight ratio
- Retains 75% of its warmth when wet compared to down
- Easy care and machine washable
- Tumble dry to regain loft and reactivate the DWR
- High loft with excellent shape retention for a down-like look
FEI S-form (Only in our Borealis and Solus Jackets)
Taking its name from the Stratiform cloud type - this is a flat sheet of wadding of voluminous, thermal insulation constructed from a blend of fine & hollow fibres, which trap air, offering excellent insulating capacity even in wet conditions.
- 92% recycled polyester content
- Superior warmth to weight ratio
- Retains 75% of its warmth when wet compared to down
- Easy care and machine washable
- Tumble dry to regain loft and reactivate the DWR
- Lightweight and packable
