A 20,000mm Waterproof Baseline
Waterproof performance is measured in millimeters of hydrostatic head — the column of water pressure a fabric can resist before moisture penetrates the membrane. KJUS sets that threshold at 20,000mm across every garment in the men's golf rainwear collection, a standard twice what the performance category typically demands. When conditions deteriorate on the course, protection is already engineered in.
The Rain Rescue 2.0: Ready for Any Forecast
The Rain Rescue 2.0 Jacket is designed for the round where the forecast changes between holes. The 2.5-layer jacket packs into its own pocket, lighter than a sleeve of golf balls, and deploys a 36K breathable membrane that pairs full waterproof protection with eco-conscious carbon capture technology. When conditions turn, the Rain Rescue 2.0 zips on without interrupting the round.
The Pro 3L 3.0: Built for Sustained Rain
For the golfer who plans a tee time regardless of the forecast, the Pro 3L 3.0 Jacket delivers 20,000mm waterproofness alongside 30,000g/m²/24hr breathability: a combination engineered to resolve the performance tension between protection and airflow. Body-mapped Hyper 3D Stretch panels move through the full swing unrestricted. An engineered rain gutter system at the wrists channels water away from the hands and grip. The matching Pro 3L 3.0 Pants feature magnetic shoe visors that eliminate bulk over footwear, completing a system built for high-performance play in sustained rain.
Waterproofing, Breathability, and the Balance Between Them
The central engineering challenge in performance rainwear is resolving the tension between waterproofing and breathability: waterproofing builds barriers, while breathability requires controlled permeability. KJUS golf rainwear is built to address both without compromise. The Pro 3L 3.0 collection achieves 30,000g/m²/24hr breathability, drawing moisture vapor outward while maintaining a full barrier against incoming water. The result is a garment that performs in sustained rain without trapping heat or moisture inside the shell.
