Built for the golfer who refuses to head indoors, the Under Armour Storm Midlayer ½ Zip is a versatile mid-layer sweatshirt that keeps you warm, dry, and completely unrestricted. Its mid-weight ColdGear® construction traps heat with hollow fibres that are lighter than solid fibres, so you get serious warmth without the bulk. UA Storm technology then locks out light rain and drizzle without any sacrifice to breathability, making this sweatshirt the ideal piece for unpredictable on-course weather. Whether you need a standalone layer on a crisp morning or a performance mid-layer under a waterproof jacket, the Storm Midlayer ½ Zip has you covered.
UA Storm is Under Armour's proprietary water-repellent finish that causes rain and light drizzle to bead up and roll straight off the fabric surface. Critically, it does this without sealing the fabric or blocking airflow, so the garment remains fully breathable during high-output activity. The treatment used on the Storm Midlayer ½ Zip is fluorine-free, eliminating harmful PFAS chemicals from the production process and making it a more eco-conscious option for environmentally aware golfers. On the course this means you can play through a shower without carrying the extra weight of soaked fabric — the Storm finish keeps the garment feeling light and dry throughout.
ColdGear® is Under Armour's cold-weather performance fabric system, and in this mid-weight configuration it strikes the ideal balance between insulation and packability. Hollow fibres trap a layer of warm air close to the body — much like down insulation — but at a fraction of the bulk and weight of traditional options. The outer face is smooth and fast-drying, shedding moisture quickly, while the inner face features a soft brushed finish that feels comfortable directly against a base layer. The result is a sweatshirt that punches far above its weight in terms of warmth-to-bulk ratio, keeping you comfortable from the first tee to the eighteenth green.
Unlike rigid midlayers that can restrict your backswing or limit follow-through, the Storm Midlayer ½ Zip is engineered with a 4-way stretch fabric construction that expands and recovers in every direction — horizontally, vertically, and diagonally. This means the garment moves precisely with your body rather than fighting against it, so your natural swing mechanics are never compromised. The 12% elastane content in the 88% polyester blend is the secret to this elasticity, providing a secure, body-following fit without feeling tight or constrictive. Whether you are driving from the tee, reaching for a bunker shot, or bending to read a putt, the fabric adapts seamlessly.
The large front zip opening is one of the most practical design details on the Storm Midlayer ½ Zip. It allows you to pull the garment on or off quickly even while wearing a glove, and gives you fine-tuned ventilation control during fluctuating on-course temperatures. Zip it fully for maximum warmth on a cold morning, or drop it down to release heat after a long walk uphill — the choice is always yours. The loose fit also means this sweatshirt sits comfortably over a thermal base layer without riding up or bunching, making it an integral piece in a proper cold-weather layering system alongside a waterproof outer shell.
