Waterproof Overtrousers Designed for Wet, Cold Days

When the weather’s wild and the work won’t wait, these men’s waterproof overtrousers from Kaiwaka’s Stormforce 2025 range offer serious protection.
Designed for outdoor jobs in harsh conditions, they combine next-level waterproofing, durability and comfort, all in a fit that’s made to move.

Constructed with mechanical ripstop fabric that stops snags becoming tears, thanks to its seam-fused construction, and Kaiwaka’s trusted Twin-skin technology, these trousers are waterproof, windproof and breathable.
The mesh lining at the base adds ventilation, keeping you cool, while the jean-style cut keeps things flexible as you go about your day.

The elasticated step-lock waistband offers a secure fit over layers, with cutaway ankles and dome closures to seal comfortably over boots.
Watertight hip pockets keep essentials dry, and the fabric is resistant to oil, fat, and farm chemicals, so they're ideal for everything from shifting bales to hose-down jobs.

Comfortable to wear in temperatures down to -10°C, they’re ready for early starts, wet fields, frosty mornings and long days outdoors.
