FASTEN was started by two moms (Jill and Alexis - hi!!) who struggled with their daughters' wet swimsuits at the pool. Not satisfied with the other swimsuit options available, they set out to create a smarter one-piece that would make life easier for girls and their moms everywhere!
FASTEN provides the perfect on-off solution for swimsuits and leotards. Our patented design features hidden magnets and snaps at the waist, eliminating the need to remove the swimsuit or leotard when it's time for a diaper change or bathroom break! PLUS, there's a hidden magnet in the back (sizes 2T and up) to keep the flap up and out of the way! We have some awesome videos showing FASTEN in action - see them here: HOW IT WORKS.
Yes, we would never put our own children in anything we believed was unsafe. All of our magnets are encased in plastic and then sewn into layers of fabric, making them inaccessible to children and even adults without some serious tampering and the use of a scissor. (To see how our magnets are sewn into our garments, watch this video.) We strictly follow the safety regulations set forth by the Consumer Product Safety Commission (CPSC). For more information, see SAFETY.
Only that she'll be back to the fun faster after using the bathroom! During our design and testing phase, kids were able to swim, play and dance normally. We always recommend that children be monitored closely around pools and/or oceans, lakes, etc. If you have any concerns about magnetic fields within a specific area, please contact the owner or your physician.
FASTEN swimwear and dancewear is manufactured in the United States and in China.
As moms, we know the value of time and why shopping online can be so useful! We also know it can be tricky when it comes to finding the right size. We strongly recommend using the size chart located on every product page. If your child is toward the end of a range, we suggest sizing up. If you are still unsure, we are happy to help! Email us anytime at firstname.lastname@example.org and we will happily assist. If you are looking for a more immediate answer, you can message us on Facebook and we will do our best to get right back to you.
Caring for your FASTEN swimsuits and leotards is easy! We recommend hand washing in cold water with mild detergent. Drip dry or lay flat to dry. For more information, see GARMENT CARE.
We recognize that we wouldn’t be where we are today without the help of others, so it has always been a goal of ours to pay it forward, in any way we can. Being in the swimwear industry, it’s easy to take water for granted. But according to Water.org, 663 MILLION people (that’s 1 in 10!) lack access to safe water; 2.4 BILLION people (that’s 1 in 3!) lack access to a toilet. Water.org is dedicated to changing this, and we want to be a part of it. FASTEN has committed to featuring one swimsuit a month in which we will donate 3% of every sale to Water.org. Learn more here.
