A performance-led outerwear piece engineered with Italian insulation specialist Thermore® – marking a new push towards high-spec, responsibly designed synthetic fill in the premium outdoor market.
The jacket is built around Thermore®’s EcoDown®, the company’s flagship recycled synthetic insulation. Made entirely from post-consumer PET bottles, EcoDown® is designed to replicate the loft, softness and packability of natural down while outperforming it in wet conditions.
Unlike traditional down, which can collapse when damp, EcoDown® retains thermal performance thanks to its hydrophobic fibres – a feature increasingly sought after by retailers as consumers look for reliable warmth without animal-derived materials.
Landing in Desert Taupe and Black Beauty, the Biome Jacket mirrors Portal’s clean aesthetic, offering a slightly cropped silhouette, streamlined panelling and practical detailing geared towards both everyday wear and cold-weather hiking.
The jacket is filled with 150gsm EcoDown®, calibrated to provide static warmth in low temperatures while preventing overheating during light activity.
Other details include breathable underarm panels, multiple zip pockets, a two-way front zip, an adjustable hood and a packable design that stows into its internal dump pocket. A size medium weighs 560g.
