Craghoppers has changed the active ingredient in their insect-repellent clothing: they now use plant-based eucalyptus citriodora oil (biocide) as the active ingredient. It is milder than previously used active ingredients but helps prevent insects from landing and staying on the fabric surface. A stretchy fleece hoodie like this is a versatile garment. It provides warmth on cool summer evenings and is also suitable for layering. - Normal fit - Insulating, moisture-wicking fabric - Odor-control treatment - Two zippered pockets - Full-length zipper - Craghoppers Wash & Wear product: easy-care, no ironing required The active ingredient complies with the European Biocidal Products Regulation 528/2012/EU. It is certified at level 1 by ZDHC (Zero Discharge of Hazardous Chemicals), and the manufacturer is seeking certification at level 3.
