We've put our Unshrinkable Carefree Tees to the test, in the lab and in the field. And we're glad to say our unshrinkable t-shirts passed with flying colors. What's more, the 100% cotton fabric resists wrinkles, fading, pilling and shrinking, so our shirt keeps its true-to-size fit while maintaining its comfort and softness. No wonder it's been a customer favorite for as long as we've been making it.
