Product information & specifications
Harkie DEFIANCE Waterproof Trousers – Hi-Vis Orange
Made from tough, lightweight, and breathable fabric, the Harkie DEFIANCE Waterproof Trousers in Hi-Vis Orange are engineered specifically for arborists, incorporating new and improved user-influenced features. These trousers offer exceptional protection in wet weather, being extremely waterproof, highly breathable, and remarkably durable. The tough, lightweight, and breathable fabric ensures comfort and performance during demanding work, while the hi-vis orange provides excellent visibility for enhanced safety on the job.
Their extreme waterproofing keeps you dry in the most challenging wet conditions, and high breathability prevents overheating, maintaining comfort during active use. With durable construction, these trousers are built to withstand the rigours of professional arboriculture, and their user-influenced design incorporates practical improvements based on feedback from working arborists.
Key Features
- Made from RainBlok, Harkie's bespoke high-performance fabric for waterproofness and breathability
- Extremely tough reinforced knee and ankle patches constructed from TuffStitch technical fabric
- Extra-long Velcro opening leg gussets make them very easy to pull on over the top of boots
- Cutting-edge design matches DEFIANCE smocks and jackets
- Comfortable fit with an adjustable drawstring waist
- Heat-applied chevron reflective tape
- Two spacious phone pockets with branded waterproof zips
- Rear pocket with Velcro opening
- Tough, hardwearing and lightweight
Certification Explained
These trousers conform to RIS-3279-TOM for use on the railway network, EN ISO 20471:2013 for high-visibility clothing on highways, and EN ISO 343:2019 Class 4:4 — the highest rating for both water penetration resistance and breathability under the standard.
Why Choose the DEFIANCE Waterproof Trousers?
Class 4:4 under EN ISO 343:2019 puts these among the most weatherproof and breathable trousers Harkie makes — genuinely built for a full day's wet-weather tree work rather than light showers. The extra-long Velcro leg gussets are a small but practical detail, letting you pull the trousers on over boots quickly rather than needing to remove footwear first.
