Core Heavyweight Tee

$28.00

Your worth is non-negotiable. #SolidToTheCORE

Our Core Leadership Academy shirt is here to remind you - that your worthiness is not something that is negotiated with other people or organizations. Real leaders don’t crumble under pressure—they embrace it. Core is for those who refuse to quit, back down, or settle for less. At Core, we believe self-worth is earned, not given. You don’t need permission to be confident—you need commitment to the process.

Shirt Details: If you’re looking for a thick, structured tee that’s also super soft and breathable—look no further! The Comfort Colors brand, unisex garment-dyed heavyweight t-shirt ticks all the boxes and is made of 100% ring-spun cotton. The regular t-shirt style will complement most looks and fit you to a tee.

• Direct to film (DTF) printing
• 100% ring-spun cotton

• Fabric weight: 6.1 oz/yd² (206.8 g/m²)

• Garment-dyed
• Relaxed fit
• 7/8″ double-needle topstitched collar
• Twill-taped neck and shoulders for extra durability
• Double-needle armhole, sleeve, and bottom hems
• Blank product sourced from Honduras

This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!

No returns so choose bravely and wisely! All sales are final, thank you for supporting us.
