{"product_id":"core-strength-kids-t-shirt","title":"Core Strength Kids T-Shirt","description":"This lightweight kids tee brings a playful spark to everyday wear. A cheerful avocado character lifts tiny dumbbells across the chest, cheeky text reading “I need more core strength” beneath—cute, active, and just a little silly. Soft ring-spun cotton and a classic fit keep movement easy for school, playdates, or backyard adventures. The collar holds its shape, shoulder tape prevents stretching, and the tear-away label keeps things comfortable against little necks. Breathable, light fabric layers well under a hoodie or stands alone on warm days—made to move with kids who like to laugh and stay busy.\u003cbr\u003e\u003cbr\u003eProduct features\u003cbr\u003e- 100% ring-spun cotton for solid colors; heather options 90\/10 cotton\/poly for softness\u003cbr\u003e- Lightweight fabric (4.4 oz\/yd²) — breathable and comfortable for active kids\u003cbr\u003e- Ribbed knit collar with seam and shoulder tape for shape retention and durability\u003cbr\u003e- Tubular knit (no side seams) for a smooth look and reduced fabric waste\u003cbr\u003e- Tear-away label, classic fit, runs true to size; complies with safety and flammability standards\u003cbr\u003e\u003cbr\u003eCare instructions\u003cbr\u003e- Machine wash: warm (max 40C or 105F)\u003cbr\u003e- Non-chlorine: bleach as needed\u003cbr\u003e- Tumble dry: medium heat\u003cbr\u003e- Do not dry clean\u003cbr\u003e- Do not iron\u003cbr\u003e","brand":"Printify","offers":[{"title":"White \/ XS","offer_id":47607260446912,"sku":"25155389565882019588","price":25.99,"currency_code":"USD","in_stock":true},{"title":"White \/ S","offer_id":47607260512448,"sku":"31327289462909665636","price":25.99,"currency_code":"USD","in_stock":true},{"title":"White \/ M","offer_id":47607260577984,"sku":"14719022953759947534","price":25.99,"currency_code":"USD","in_stock":true},{"title":"White \/ L","offer_id":47607260643520,"sku":"19858358301203400116","price":25.99,"currency_code":"USD","in_stock":true},{"title":"White \/ XL","offer_id":47607260709056,"sku":"53361558605341039885","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Sport Grey \/ XS","offer_id":47607260414144,"sku":"10711155321252217171","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Sport Grey \/ S","offer_id":47607260479680,"sku":"23885877601109171500","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Sport Grey \/ M","offer_id":47607260545216,"sku":"13967313396549381133","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Sport Grey \/ L","offer_id":47607260610752,"sku":"13233094609066539081","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Sport Grey \/ XL","offer_id":47607260676288,"sku":"69422882469920029539","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5540\/9088\/files\/20260304175744-1f117f3a-5885-6c2c-a180-4237e9827b07.png?v=1772647118","url":"https:\/\/gymnastshirts.com\/products\/core-strength-kids-t-shirt","provider":"Gymnastics Life Shirts","version":"1.0","type":"link"}
