The Stone Island Boys 30/1 Cotton Jersey T-Shirt in Green is a short-sleeve 100% cotton T-shirt for boys aged 2 to 14, made in Tunisia, part of the AW2026 Stone Island Junior collection. The 30/1 in the name refers to the yarn count — a single-ply cotton yarn spun to a 30-count weight, which produces a finer, smoother, and lighter fabric than standard T-shirt jersey. It carries the Stone Island compass badge and has an organic certification, meaning the cotton meets a verified environmental standard. It sits in the Mini-Me collection, indicating there is an equivalent adult Stone Island piece in the same colourway this season.

Green is one of the more distinctive colourways in the Stone Island Junior AW2026 T-shirt range. It works within the season's broader earthy and outdoor-influenced palette and pairs naturally with navy, khaki, brown, and black. For boys in the older age range (10–14) who are aware of Stone Island as a brand, a green T-shirt in a recognisable silhouette with compass badge reads as considered rather than generic. For younger boys, the colour is practical and holds well in cotton at this specification. This is a designer boys' T-shirt with a specific fabric construction — it's not a standard cotton tee.

Buying Advice

• Fit: Stone Island Junior T-shirts in this construction tend to run with a clean, slightly fitted silhouette — finer jersey sits closer to the body than a heavier cotton. If your son prefers a more relaxed fit, sizing up gives more ease without the T-shirt looking oversized. True-to-age works well for a neat, intentional look.
• Care: Machine wash at 30–40°C, inside out, to preserve the green dye and protect the compass badge. Fine cotton jersey is more prone to distortion at higher temperatures — avoid washing at 60°C or above. Air dry flat or tumble dry on a low setting. Do not iron directly over the badge.
• Layering: The lighter weight of 30/1 jersey makes this T-shirt suitable for layering under a sweatshirt, zip-through, or lightweight jacket without adding noticeable bulk. It also works as a standalone top in milder AW conditions — the finer fabric is more comfortable in transitional weather than a heavier cotton T-shirt.
