The Under Armour Storm SweaterFleece ½ Zip junior sweatshirt combines the comfort and warmth of a classic fleece with the all-weather performance young athletes demand. Built with UA Storm water-repellent technology and a stretchy, brushed-interior SweaterFleece fabric, it keeps kids warm, dry, and free to move through every training session or outdoor activity. The half-zip design makes layering effortless, whether worn as a mid-layer on cold game days or as a standalone top during autumn practice.
Designed for junior athletes who refuse to let the weather slow them down, this sweatshirt blends durable woven overlays with a comfortable fleece construction — delivering long-lasting performance season after season.
UA Storm is Under Armour's proprietary water-repellent finish that forms a protective barrier on the outer surface of the fabric, causing rain and moisture to bead up and roll off rather than soaking through. Critically, the treatment does not block the fabric's pores, so the sweatshirt remains fully breathable — sweat vapour escapes freely even as rain is repelled. This makes it ideal for cool, wet training days, morning practices, and unpredictable autumn weather where a fully waterproof shell would feel overly restrictive. The UA Storm coating is applied as a fluorine-free DWR (Durable Water Repellent) treatment, meaning it provides robust protection while minimising environmental impact compared to older fluorine-based treatments.
The SweaterFleece fabric is engineered to bridge the gap between a traditional knit sweater and a performance fleece. Its outer surface mimics the classic texture and appearance of a sweater, giving the garment a smart, versatile look that transitions easily from training to everyday wear. The interior is soft and brushed for immediate warmth against the skin, while a degree of four-way stretch is woven into the fabric to deliver unrestricted mobility. Whether a young athlete is swinging their arms during warm-ups, crouching in a fielding position, or simply wearing it on the way to school, the SweaterFleece adapts to every movement without pulling or restricting. The body is constructed from 100% polyester, ensuring the fleece is lightweight, quick-drying, and easy to care for.
High-wear zones on any active youth garment — particularly the shoulders and chest — are subject to repeated abrasion from backpack straps, friction, and daily activity. Under Armour has addressed this with strategic woven overlay panels in exactly these areas. The woven overlays are made from an 87% polyester / 13% elastane blend, giving them additional strength and a degree of stretch to complement the main SweaterFleece body. This reinforcement significantly extends the lifespan of the sweatshirt, ensuring it holds up to the demands of an active junior lifestyle. The overlays also add a subtle textural contrast that contributes to the garment's premium, layered aesthetic.
The half-zip construction is a deliberate design choice for active wear: it allows the wearer to regulate body temperature quickly by opening the zip slightly for ventilation or pulling it fully closed for maximum warmth retention. The banded bottom hem and cuffs are elasticated to seal in warmth, prevent the sweatshirt from riding up during activity, and maintain a clean silhouette. A drop-in chest pocket with a secure zip closure provides a convenient place to stow a phone, keys, or small accessories, keeping hands free and pockets accessible without affecting the garment's fit or freedom of movement. Together, these details make the sweatshirt as practical as it is comfortable.
