British sustainable outdoor clothing brand Finisterre has won an award for its climate-positive BioSmock insulation layer.

The water repellent and windproof BioSmock features an outer shell made with new PrimaLoft Bio technology, a PFC-free synthetic material woven by Amaterrace of Japan, which is biodegradable on land and in the sea.

The jury at the ISPO Munich sporting goods trade fair, which gave the garment the Gold ISPO Outstanding Award in the Insulation Apparel Category, said: “The Finisterre BioSmock is the leading example of the circular economy in performance apparel. It’s a practical insulation layer that uses the most advanced PrimaLoft Bio technology combined with HD Wool Active Insulation to create comfort in almost every condition. [It] champions the end-of-life: woven compostable shell and thermoregulating insulation. When all other items are trying to reduce their environmental footprint, this garment has the potential to be climate positive through using regenerative practices.”

The insulating layer is provided by HD Wool in the form of a wool/PLA compound that also decomposes safely in marine environments when microbes are introduced. HD Wool Active Insulation uses a blend of non-Merino wool known for its greater physical durability.

Furthering its naturally sustainable moisture management and thermo-regulating benefits, HD Wool Active Insulation is sourced from farmers who have started the re-generative agricultural process by having their land subjected to an annual Ecological Outcome Verification set forth by the Savory Institute to show progress in land-to-market objectives – namely restoring the biodiversity of the land, improving soil health, creating better natural irrigation, and sequestering carbon.

Among other features is a lack of zippers, as none of the biodegradable versions on the market would decompose fast enough alongside the rest of the garment. The kangaroo front pocket, where adjustments can be made from PLA poppers, serves as a simple storage/ hand warming area.
