Finisterre Engineered 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.

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

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.
