All of our adult t-shirts are tri-blend for ultimate comfort and durability while on the caching trail. Baseball shirts are a blend. Kid’s shirts are 100% cotton and heathers are a blend. Do you want your caching name on the back of a shirt? Or a trackable number? Do you love a pattern but want it in a different style? All of our shirts are customizable (at a modest fee) and available in unisex, women’s, and kid’s styles even if they are not specifically shown on the site. Just phone-a-friend – and by phone we mean send us a message – and we’ll make sure you get what you need!
