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.

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. Our new A-form insulation is now 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.

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
