A modern twist on the classic Retention Jacket, the KJUS Regulator Men's Jacket combines bonded quilting on the front with a lightweight, warming insulation for outstanding on-course comfort. The entire jacket is built with four-way stretch fabric that moves in every direction with your swing, while a moisture-wicking lining keeps you dry throughout the round. Crafted from ultra-soft, recycled synthetic materials and finished with a PFC-free DWR treatment, this jacket is the ideal mid-layer for mild to cool days on the golf course.
The KJUS Regulator jacket is finished with a Durable Water Repellent (DWR) coating that is completely free of PFCs (perfluorinated compounds) — harmful chemicals commonly found in older waterproofing treatments. The fabric is coated with a durable polymer barrier that reduces surface tension, causing water droplets to bead up and roll off the surface rather than soaking in. This eco-conscious approach means you stay dry in light rain and morning dew without compromising on environmental responsibility. For optimal long-term performance, the garment can be machine-washed and the DWR treatment re-activated according to the care instructions.
The moisture-wicking lining works as an active thermal management layer, pulling sweat and body moisture away from the skin and dispersing it across a larger surface area to accelerate evaporation. This keeps the microclimate between your body and the jacket consistently dry and comfortable, even during the physical exertion of a full 18-hole round. The result is a jacket that feels fresh from the first tee to the final putt, preventing the clammy discomfort that can arise in warmer stretches of cool-weather play.
The upper front panel of the Regulator jacket is filled with a new generation of recycled synthetic down fibres — engineered to retain more warmth than older synthetic fills while being significantly easier to care for than natural down. Unlike natural down, these fibres maintain their insulating properties even when exposed to moisture, and they dry considerably faster after washing. The use of recycled polyester fibres also reflects KJUS's commitment to sustainable materials, reducing the demand for virgin resources without sacrificing the performance golfers expect. The lower front panel complements this with a targeted synthetic insulation for full torso warmth coverage.
Every panel of the KJUS Regulator jacket is constructed from a high-stretch, high-recovery fabric blend that expands and retracts in sync with the body's movements. Four-way stretch means the fabric gives in all directions — horizontally, vertically, and diagonally — so there is never any pulling or restriction during the backswing, downswing, or follow-through. This exceptional elasticity is paired with an ultra-soft hand feel, making the jacket as comfortable as a mid-layer fleece while offering significantly better wind and moisture resistance. The result is a jacket that disappears on the body, letting you focus entirely on your game.
The Regulator jacket features precision-bonded quilting across the front panels, a technique where the fabric layers are fused together with adhesive rather than stitched through. This eliminates the cold spots that can occur at needle punctures in traditionally stitched quilted garments, maintaining thermal efficiency across the entire front surface. The clean bonded seams also contribute to the jacket's sleek, contemporary aesthetic, giving it a refined look that transitions effortlessly from the golf course to casual post-round wear. KJUS branding is tastefully placed at the inner and outer collar and the back shoulder.
The Regulator jacket is cut to a standard fit through the chest, waist, and hem, offering a clean, athletic silhouette that works across a broad range of body shapes. The mid-length design — reaching to the hip — provides practical coverage over golf trousers and shorts alike, keeping core warmth where it matters most during a round. Classic sleeves taper to a fitted, wrist-length cuff, preventing cold air from entering at the wrist while maintaining a streamlined profile under a waterproof outer layer if needed. This versatile cut makes the Regulator jacket equally at home as a standalone piece on a cool autumn morning or as an insulating mid-layer in colder conditions.
