A consistent bestseller in the KJUS golf collection, the Men's Retention Jacket delivers the ideal combination of lightweight warmth and unrestricted movement. It features super lightweight, full-stretch insulation on the front panel, while the back and sleeves are crafted from soft, highly stretchable fabric that moves with every swing. With an exceptionally high warmth-to-weight ratio, this jacket is the go-to choice for mild to cool days on the course — keeping you focused on your game rather than the temperature.
The heart of the Retention Jacket's warmth is KJUS's own FAST Thermo Core™ technology — a high-performance stretch insulation engineered to trap warm air close to the body while simultaneously wicking moisture away. Used exclusively on the front panel where insulation is needed most, the 50 g fill weight provides meaningful warmth without adding excessive bulk or weight. The insulation flexes with your body rather than fighting it, so it never impedes your swing mechanics. It is the ideal solution for golfers who want the thermal benefit of a padded jacket combined with the mobility of a softshell.
While the front provides insulation, the back and sleeve panels are constructed from a dedicated 4-way-stretch fabric that expands and retracts in sync with every body movement. This engineering decision is specifically tailored for golf: the areas of the jacket that experience the most stress during a full swing are the very panels with the highest elasticity. The result is a jacket that feels like a second skin during your backswing and follow-through, with zero restrictive pull or bunching. Redefining stretch capacity in every layer and any direction, this fabric is a signature element of KJUS performance outerwear.
The outer surface of the Retention Jacket is finished with a Durable Water Repellency (DWR) treatment that causes water droplets to bead up and roll off the fabric instantly, preventing the jacket from becoming saturated in light rain or morning dew. Crucially, this DWR treatment is entirely free of PFCs (per- and polyfluoroalkyl substances) — harmful chemicals commonly used in traditional water-repellent finishes. The eco-conscious formulation provides the same level of water-repellent protection without environmental compromise. To maintain peak performance over time, simply machine wash and tumble dry on a low setting to reactivate the DWR coating.
The interior of the jacket is lined with a dedicated moisture-management fabric composed of 89% polyester and 11% elastane. This lining uses unique fiber structures designed to vigorously draw perspiration away from the skin's surface and transport it to the exterior for rapid evaporation — keeping you feeling dry and comfortable even during physically demanding rounds. The addition of elastane in the lining ensures it retains its own stretch quality, working harmoniously with the outer fabric to deliver unrestricted movement without any internal friction or bunching against your base layer.
