Care & Environmental Advice

Environmental considerations

​Wear more, wash less: it’s every busy adventurer’s dream… We apply Polygiene™ to garments so that they smell less with wear and need washing less between use: ideal for that multi day getaway (and you’re doing your bit for the environment too). Polygiene ™ is a silver based treatment that we apply during fabric production. The silver chloride prevents the growth of the bacteria that makes your clothes pong without interfering with the skin’s natural bacteria flora, so it’s comfortable and safe next to your skin. Polygiene ™ is bluesign ® approved (meeting the highest environmental standards) and lasts as long as your clothes do, so you’ll never need to reproof them. The catch? There isn’t one! You can wear this garment day in, day out, and day back in again without causing a stink – winner!​
