Great find!

After struggling to squeeze my infant daughter into bathing suits last summer, I was looking for something with a full zipper for this next swimsuit season. I found SwimZip, and it's been awesome! The full zipper has made it so much easier to get the suit on my 97th percentile for weight 13 month old daughter - she doesn't fight getting dressed, and I don't have to worry about sun protection. Plus, the design is super cute! She wore it to the beach for the first time yesterday and had a blast! It was easy to move in, and I appreciated only having to apply a small amount of sunscreen (face, feet and neck). After sending a beach picture to friends, they all wanted to know where I got the suit! Highly recommend!

Great for an amputee

My 4 year old is a new bilateral amputee due to an illness. We live on a lake and take our kids to the beaches often. Sand- and skin grafts don’t mix too well. Rooftop shout out for making a full body suit. We are able to cover his scars/skin grafts on his arms and legs and we don’t have to worry about him scooting around in the sand on the beaches!

Soft and Easy to Use

Love this pattern! The full zipper is amazing for putting on a wiggly 7 month old!

Runs true to size, I sized up and it is a little big and long.

Love it!

I bought this for my almost 3 year old son. Perfect for beach days! The less sunscreen I have to use on a toddler the better lol!
