{"product_id":"stone-island-boys-seamless-tunnel-nylon-down-puffer-jacket-in-black","title":"Stone Island Boys Seamless Tunnel Nylon Down Puffer Jacket in Black","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eStone 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Stone Island Junior\u003c\/li\u003e\n\u003cli\u003eColour: Multicoloured\u003c\/li\u003e\n\u003cli\u003eConstruction: Seamless Tunnel Quilting\u003c\/li\u003e\n\u003cli\u003eFill: Down\u003c\/li\u003e\n\u003cli\u003eOuter: Nylon (water-resistant)\u003c\/li\u003e\n\u003cli\u003eMade in Vietnam\u003c\/li\u003e\n\u003cli\u003eGender: Boys\u003c\/li\u003e\n\u003cli\u003eSizes: 2, 3, 4, 6, 8, 10, 12, 14 Years\u003c\/li\u003e\n\u003cli\u003eSeason: AW2026\u003c\/li\u003e\n\u003cli\u003eFeatures: Seamless tunnel construction, down fill, water-resistant, compass badge, sustainable\u003c\/li\u003e\n\u003cli\u003eCollections: Mini-Me\u003c\/li\u003e\n\u003cli\u003eCategory: Boys' Designer Down Jacket\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Stone Island Junior","offers":[{"title":"Black \/ 10 Yrs","offer_id":48201166029014,"sku":"STOA6020166129","price":540.0,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 12 Yrs","offer_id":48201166061782,"sku":"STOA6020166130","price":540.0,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 14 Yrs","offer_id":48201166094550,"sku":"STOA6020166131","price":605.0,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 2 Yrs","offer_id":48201166127318,"sku":"STOA6020166132","price":435.0,"currency_code":"GBP","in_stock":false},{"title":"Black \/ 3 Yrs","offer_id":48201166160086,"sku":"STOA6020166141","price":435.0,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 4 Yrs","offer_id":48201166192854,"sku":"STOA6020166133","price":435.0,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 6 Yrs","offer_id":48201166225622,"sku":"STOA6020166134","price":485.0,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 8 Yrs","offer_id":48201166258390,"sku":"STOA6020166135","price":485.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/1004\/2838\/files\/STOA6020_BLACK_1.jpg?v=1786630447","url":"https:\/\/www.childsplayclothing.co.uk\/products\/stone-island-boys-seamless-tunnel-nylon-down-puffer-jacket-in-black","provider":"Childsplay Clothing","version":"1.0","type":"link"}
