    Every order gets a physical postcard with a unique serial code. Using your special code on our website allows you to get a behind-the-scenes look at a REAL turtle being rehabilitated at the sea turtle rescue!

    Shelly Cove's mission statement is to donate a *minimum* of 10% of net profits annually to sea turtle rescue. In most cases, we are able to donate more - even up to 1/3 of profits!

    So far, we have donated over $200,00 to sea turtle rehabilitation, and other great causes like clean water initiatives, local food banks, scholarship funds, and more!

    Only the best! We use premium garment-dyed, 100% cotton tees. All printed in-house to give you the best garment possible. This prevents shrinking, and gives you a shirt that will last years!

    Mystery T!

    I ordered one for me and my daughters they couldn’t have picked better! Mine was yellow and had flowers which I loved and her shirt was her favorite teal/mint green color! We love them!

    Love it!

    I love my shirt! I was having trouble picking which design I liked best so decided to let them pick for me. I was a little nervous but I ended up with a super cute blue shirt! The shirt is so soft too I love it! I also love how you get the turtle tracker with an order!

    Love!

    I was worried about getting an orange or yellow shirt and I ended up getting a yellow shirt, "Happy Daises." However, I love it. It's not something I would normally buy but it's super cute and I can't wait to wear it. I love the mystery when opening my package.

    Mystery shirt

    I love my mystery shirt. It’s a fantastic shade of blue. It says Shelly Cove on front in white and on back is a sea turtle out for a swim. I love him so much. I was going to order this design but it was sold out. I usually wear V neck shirts because crew neck come up to high and choke me. This one was perfect tho. I’m going to wear it to the aquarium!
