HD Wool® Active Insulation™ is a natural, eco-friendly and biodegradable internal garment insulation for breathable performance and unmatched moisture management


    HD Wool® is lightweight and breathable. Your wool insulated jacket naturally adjusts to your body's thermal and moisture balance, improves perspiration comfort and keeps you drier from the inside.


    Our unrivalled experience in the world of wool places us in a perfect position to identify ETHICALLY grown wool, and provide a TRANSPARENT and TRACEABLE route to the source, giving our customers peace of mind that their wool is shorn from happy sheep!


    HD Wool® insulation is used by the leading outdoor clothing brands worldwide, to create highly resilient, customisable, hard-wearing but light outdoor performance wear.


    Natural, biodegradable wool wadding for breathable performance, resilience and unmatched moisture management.


    HDWool® insulation was developed specifically for energetic outdoor activities, as an alternative to synthetic and down insulation. Whatever the season, however intensive the activity, this exceptionally lightweight insulation layer naturally adjusts to your body's thermal balance, improves perspiration comfort and keeps you drier from the inside.


    The technology of HDWool® is distinctively different from other traditional insulation materials because its main component is our hand-selected WOOL. Our specially-selected wool are complex fibres, composed of proteins that bring natural flexibility and unmatched performance characteristics - something that simplistic inert synthetic fibres are unable to reproduce.


    HDWool® Active Insulation™ was created by the team with almost 130 years of experience in the wool industry. We are strongly positioned globally and strategically within the market, which enables comprehensive management of all areas of the wool supply chain, providing a transparent and traceable route to the source, as well as reflects high standards for farm management and animal welfare.


    HDWool® keeps the cold out, whilst allowing perspiration vapour to escape during exercise and provides a maximum comfort by maintaining a steady body temperature.

    HDWool® Active Insulation


    Wool is naturally hygroscopic. This means that the fibres preferentially pull moisture out of the air until they reach saturation. This can take considerable time because wool can absorb 33% of its own weight of water before it feels damp and allows condensation to take place in the air trapped within garment insulation. Many available insulating materials, such as down or synthetic, are good at keeping cold out, but they fall short when managing the moisture produced by an active body. The difference between synthetics and wool is that wool absorbs condensation, whereas synthetic fibres hold the water on the surface of the fibre, which dramatically reduces the insulation capability of synthetics.

    The human body relies on the evaporation of sweat to remain comfortable and prevent overheating. HDWool® insulation provides a naturally adaptive moisture management. It absorbs moisture from microclimate surrounding your body, keeping humidity down, and allowing you to be warm yet comfortable for longer. When you are not wearing your garment, HDWool® will give up the moisture back to the atmosphere re-charging for your next adventure. Precisely as nature intended!

    HDWool® insulation contains hand-selected, highly resilient wool, that retains superior and longer lasting insulation properties. The natural crimp and resilience in HDWool® maintains shape and performance for much longer than other insulation materials. We’ve combined a little biodegradable polymer into the wool wadding to allow it to be machine washed. No unpleasant chemicals are used in this process, something which we are very proud of.

    We use our knowledge of and passion for wool to develop nature’s best kept secret into an innovative and effective insulation. Wool offers the most insulation with the least amount of weight. Wool is sustainable, absorbent, washable, flame and odour resistant, as well as an entirely renewable and biodegradable natural product. It can be safely recycled at the end of its life, reducing the environmental pressure.
