{"product_id":"speed-bag-killer-t-shirt-retro-boxing-gym-tee","title":"Speed Bag Killer T‑Shirt — Retro Boxing Gym Tee","description":"Lightweight, soft, and built for action — this tee wears like a companion for anyone who lives at the bag. The bold “SPEED BAG KILLER” crest sits front-and-center in vintage-inspired varsity lettering with a punchy red accent that reads like confidence and late-night training sessions. It’s breathable ring-spun cotton with a clean crew neckline and a classic fit that layers easily under a hoodie or stands proud on its own. The subtle natural flecks on the unprocessed color add character, while tear-away labels and reinforced shoulder tape keep it comfortable through repeated rounds and washes. Wear it to the gym, the garage, or between rounds — it’s the sort of shirt that announces you take your speed and rhythm seriously.\u003cbr\u003e\u003cbr\u003eProduct features\u003cbr\u003e- 100% ring-spun cotton (lightweight 153 g\/m²) for a soft, breathable feel\u003cbr\u003e- Tubular knit (no side seams) for a smooth drape and reduced fabric waste\u003cbr\u003e- Ribbed elastic collar and shoulder tape for shape retention and durability\u003cbr\u003e- Pearlized tear-away label for itch-free comfort; DTF sleeve\/inner-neck prints where applicable\u003cbr\u003e- OEKO-TEX® STANDARD 100 certified; meets safety and material compliance standards\u003cbr\u003e\u003cbr\u003eCare instructions\u003cbr\u003e- Do not dryclean\u003cbr\u003e- Do not bleach\u003cbr\u003e- Tumble dry: low heat\u003cbr\u003e- Iron, steam or dry: low heat\u003cbr\u003e- Machine wash: cold (max 30C or 90F), with similar colors \u003cbr\u003e","brand":"Printify","offers":[{"title":"Black \/ S","offer_id":48796281798813,"sku":"10603420715771377331","price":40.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ M","offer_id":48796281831581,"sku":"20349559342627287400","price":40.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ L","offer_id":48796281864349,"sku":"29546834953351171320","price":40.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ XL","offer_id":48796281897117,"sku":"31459609815861586194","price":40.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 2XL","offer_id":48796281929885,"sku":"42178720621472666692","price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0141\/8946\/1561\/files\/2733671197267891002_2048.jpg?v=1786727163","url":"https:\/\/old-school-boxing.myshopify.com\/es\/products\/speed-bag-killer-t-shirt-retro-boxing-gym-tee","provider":"Old School Boxing","version":"1.0","type":"link"}
