Weird flex? Nah, nothing weird about this baseball-muscle to get you fired up. This shirt is made of a heavier cotton with a double-stitched neckline and sleeves for added durability. Here are the specs:

• 100% ring-spun cotton

• Sport grey is 90% ring-spun cotton, 10% polyester

• Dark heather is 65% polyester, 35% cotton

• Fabric weight: 4.5 oz/y² (153 g/m²)

• Pre-shrunk for extra durability

• Shoulder-to-shoulder taping

• Quarter-turned to avoid crease down the center

NOTE: these shirts are printed on demand by a company called Printful, which also handles the shipping. They do not offer returns or exchanges (unless an item is damaged). I do not offer returns or exchanges. ALL PURCHASES ARE FINAL, so make sure you order the correct size. If you’re debating between two sizes, I suggest you get the bigger one as these shirts tend to run *slightly* smaller than other brands. Hope that helps. Thanks and happy shopping! :)
