The FootJoy ThermoSeries Insulated Ladies Jacket is part of FootJoy's most advanced and versatile clothing layering system ever — engineered to adapt as the weather changes so you can look, feel, and play your best in any conditions. Combining T-2 ThermoLite® insulation with a technical outer-shell fabric, this jacket delivers maximum warmth without unwanted bulk, keeping you focused and comfortable even on the coldest and most unpredictable days on the course.
Its feminine, active-fit silhouette is designed to move with you through every swing, while the hybrid construction balances style, function, and athletic performance in equal measure. Whether worn as the outermost layer of a full ThermoSeries system or on its own during a crisp morning round, this jacket is equally at home on the fairway and off it.
At the heart of this jacket lies T-2 ThermoLite® insulation — a premium synthetic fill engineered to provide maximum warmth without the weight or volume of traditional insulation. The quilted construction distributes warmth evenly across the body, eliminating cold spots while maintaining a sleek, streamlined profile. This technology makes the jacket equally effective whether it is worn as the sole outer layer on a cold day or as part of a full ThermoSeries layering system when temperatures drop further. The result is a jacket that feels light and unrestrictive yet keeps you genuinely warm throughout all 18 holes.
The outer shell is constructed from a lightweight woven fabric treated with a Durable Water Repellent (DWR) finish, forming a protective barrier against wind and light precipitation. Rather than adding stiffness or noise, the woven structure remains supple and quiet during the swing, ensuring it never interferes with your tempo or feel. The DWR treatment causes water to bead and roll off the surface, keeping you dry during mist, light showers, and damp morning rounds without the need for a separate rain jacket. This dual wind-and-water protection makes the jacket a versatile companion for unpredictable golf weather throughout the season.
Strategic panels of breathable 4-way stretch fabric are integrated throughout the jacket, most notably across the arms and body, to ensure complete range of motion during the golf swing. This fabric actively wicks perspiration away from the skin to the outer surface where it can evaporate, keeping you dry and comfortable even during moments of high exertion. The stretch properties mean there is no pulling, binding, or restriction as you rotate through impact — a critical performance requirement that FootJoy has engineered specifically for active golfers. The combination of insulation and stretch makes this jacket genuinely athletic rather than simply warm.
The jacket incorporates an anti-microbial finish that actively works to inhibit the growth of odour-causing bacteria, particularly important when moisture is present during cold-weather play. This means you can wear the jacket across consecutive days or multi-round events without worrying about freshness — a practical benefit that serious golfers will appreciate. The treatment is integrated into the fabric itself rather than applied as a surface coating, giving it durability through repeated washing. Combined with the moisture-wicking properties of the stretch panels, the jacket maintains a comfortable and hygienic microclimate next to your skin throughout your entire round.
The ThermoSeries Insulated Jacket is designed as the outermost shell of FootJoy's complete ThermoSeries cold-weather system — the brand's most advanced and versatile apparel layering system ever created. The system is engineered so that each layer works in harmony: a ThermoSeries Base Layer manages moisture closest to the skin, a ThermoSeries Mid-Layer adds insulating warmth, and this Insulated Jacket seals in heat while blocking the elements. The result is a fully adaptable outfit that can be adjusted piece by piece as the temperature rises or falls during your round. Whether you need all three layers on a frosty morning or just the jacket over a light polo, ThermoSeries gives you the flexibility to always dress optimally for the conditions.
The jacket is cut specifically for the female golfer's silhouette, following the contours of the body without being restrictive. The feminine fit ensures the jacket sits neatly under a waterproof outer layer if needed, or looks polished and intentional when worn on its own. Knit collar and cuffs add a refined finish while sealing in warmth at key exposed points. The classic navy colourway is elegantly understated, working seamlessly with the rest of the ThermoSeries range as well as everyday wardrobe staples. A ThermoSeries logo at the left hem completes the look with a subtle branded detail.
