What is "Interlock"?

Think of Interlock as the "hug" of cotton fabrics. Because it is double-knitted, it doesn't curl at the edges and feels thicker and spongey compared to a standard T-shirt fabric. This makes it our number one recommendation for crawlers and toddlers who need extra padding and durability on their adventures.
