Stone Island Boys Black Seamless Tunnel Nylon Down Puffer Jacket - Size 10 Years Kids

Stone Island

The Stone Island Junior Boys Seamless Tunnel Nylon Down Puffer Jacket is a boys' designer down jacket for AW2026, available in a wide size range from 2 to 14 years. Made in Vietnam, it uses a seamless tunnel construction — a specific quilting method where the down fill is contained in continuous channels (tunnels) stitched without seams breaking through the outer shell. The result is a cleaner surface finish and fewer cold spots than traditionally quilted puffer jackets, where stitching lines can compress the fill and reduce insulation at those points. The nylon outer is water-resistant, and the down fill provides warmth-to-weight efficiency that synthetic insulation typically can't match at the same bulk. This is a genuinely warm jacket for cold weather — not a transitional layer. The multicoloured colourway gives it visual character while the plain, unprinted design keeps it versatile across casual outfits. The Stone Island compass badge sits on the sleeve. The jacket is part of the Mini-Me collection, coordinating with adult Stone Island outerwear from the same AW2026 season. It also carries Stone Island Junior's sustainability credentials for this season. Stone Island Junior sizing runs slightly slimmer and shorter than UK high-street equivalents — if your son is between sizes or broader in build, size up. For care, down jackets should be washed on a gentle cool cycle with a specialist down detergent where possible, and tumble-dried on low with a couple of clean tennis balls to redistribute the fill — or follow the garment care label for the manufacturer's specific guidance.
