The Stone Island Junior Boys Cotton Polo Sweatshirt in Navy is a boys' designer sweatshirt with one key difference from a standard crew neck: the polo collar. It's a small detail that makes the piece feel slightly more considered — smarter than a plain sweatshirt, without tipping into formal territory. The cotton construction keeps it breathable and comfortable across seasons, and the navy colourway is one of the most versatile in any child's wardrobe.

Made in Italy and carrying the Stone Island Junior Organic badge, this is a non-seasonal piece — meaning it's designed to be worn year-round rather than being tied to a specific autumn/winter or spring/summer drop. It sits within both the Mini-Me and Loungewear collections, and is available in sizes 6–14 years.

Buying Advice

• The polo collar: Unlike a standard sweatshirt, the polo neck gives this piece a slightly more structured look at the neckline. It works well for occasions where a plain sweatshirt might feel too casual — family meals out, visits, low-key smart-casual events.
• Year-round wear: Cotton (rather than fleece) means this is genuinely wearable across spring, summer and autumn. In winter it works as a mid-layer under a jacket.
• Navy as a base: Navy is one of the most forgiving colours for children's clothing — it doesn't show marks as readily as grey or lighter colours, and it pairs with almost everything.
• Fit: True to size. The polo collar sits flat and doesn't add bulk at the neck. Size up if your child prefers a relaxed fit or you want room to grow.
• Care: Machine wash at 30°C on a gentle cycle, inside out. Do not bleach. Tumble dry on low or lay flat to dry. Italian-made cotton garments generally respond well to cool washing and air drying.
