The Under Armour Storm Women's Midlayer Full-Zip is a performance-driven midlayer built for cooler days on and off the golf course. It delivers genuine warmth without unnecessary weight or bulk, thanks to hollow-fibre construction that traps heat far more efficiently than conventional solid fibres. UA Storm technology gives the outer surface a water-repellent finish that keeps you dry when the weather turns, while the fitted silhouette and four-way stretch fabric ensure total freedom of movement — so nothing stands between you and your best round.
UA Storm is Under Armour's proprietary water-repellent treatment applied directly to the fabric surface. Rather than blocking the weave with a heavy coating, UA Storm causes water to bead up and roll off the outer face of the garment, so rain and light drizzle never soak through to your baselayer. Crucially, the treatment still allows body moisture and heat to escape outward, maintaining breathability throughout your round. The result is a midlayer that keeps the elements at bay without trapping sweat against your skin — a critical balance during high-output activities like golf, hiking, or training.
The midlayer is constructed with hollow polyester fibres, which contain tiny air pockets running through the core of each strand. These air pockets act as insulation — trapping body heat and reflecting it back — in the same way that down clusters work, but with none of the performance loss when wet. Compared with conventional solid fibres of the same weight, hollow fibres deliver a noticeably higher warmth-to-weight ratio. This means you stay genuinely warm on cold mornings without wearing a heavy, restrictive layer that limits your swing or feels uncomfortable after 18 holes.
The mid-weight knit fabric uses a dual-layer construction — two distinct fabric faces engineered for different jobs. The interior surface is soft and brushed, sitting comfortably against your baselayer and providing a plush, warm feel from the first moment you put it on. The exterior surface is smooth and fast-drying, designed to shed light moisture quickly and dry rapidly after a shower. This combination means you never feel damp or clammy inside, even in changing conditions, making the midlayer equally effective as a standalone piece or as part of a layering system.
The 88% polyester / 12% elastane blend gives the fabric genuine four-way stretch — it moves with you both horizontally and vertically, adapting to your body as you rotate, reach, or swing. For golfers this is especially important: a midlayer that resists movement or pulls across the shoulders at the top of the backswing is a distraction. This fabric offers a full, unrestricted range of motion throughout the entire swing, while recovering instantly to its original shape after each movement so the fit stays consistent hole after hole.
The water-repellent treatment on this midlayer is entirely fluorine-free, meaning it contains none of the PFAS chemicals (per- and polyfluoroalkyl substances) that have raised environmental concerns in the textile industry. Under Armour's fluorine-free DWR (durable water-repellent) finish achieves strong water-beading performance while being a more sustainable and responsible choice for consumers who care about their environmental footprint. This treatment also holds up well through repeated washing when the garment is laundered correctly — zipped up, turned inside out, and tumble-dried on a low setting.
The Storm Midlayer Full-Zip is cut in Under Armour's fitted specification — a streamlined shape that is close to the body without being restrictive. A waist-shaping construction adds a subtle taper through the torso, creating a flattering feminine silhouette that avoids the boxy, shapeless look of many performance midlayers. The full-length zip makes it easy to put on and take off between holes or during warm-up, and the overall profile is slim enough to layer cleanly under a waterproof jacket without bunching or adding visual bulk.
