The grooviest swimsuit in the universe!

From the Riviera to the neighbourhood kiddie pool, your baby will have the cutest bum around. And rest assured - nobody will ever have to empty the pool because of your little darling! Fashion and peace of mind - what better combination can there be in a baby swimsuit ....

Engineered with painstaking attention to detail and functionality:

  • A trim and attractive design that has a terrific fit on any baby
  • Interior polyester mesh for easy clean ups
  • Coated nylon layer sandwiched inside that will hold in the messiest stuff a baby can throw at you!
  • Fun cotton prints on the outside
  • Adjustable hook and loop closures for a snug and comfortable fit
  • Stretchy soft lycra bindings to protect baby’s tender skin
  • UPF 50 - maximum UV protection due to the special way the fabric is woven (no chemicals required!)

What should you put inside the SWIMMI?

Absolutely nothing!

Does the Swimmi absorb pee?

No. Swim diapers are designed to hold messes in, not to absorb liquid. When you put an absorbent diaper in a swimming pool, it gets soaking wet – it’s no fun frolicking with a soggy bottom! When out of the water, you can add absorbency by inserting a doubler.

Can you use this pant as a waterproof diaper cover as well?

No. The Swimmi is specially designed for use as a swim diaper. It may look like other wraps, but it's not meant to work like one!

The SWIMMI is made with careful attention to detail in our own wonderful factory in Montreal, so that we are assured of good quality and fair labour practices. Most of the fabrics and components we produce with are sourced in North America and all are guaranteed lead, phthalate and BPA free.

Does Its Job

I prefer Swimmis to all other swim diapers! I like the adjustability of the velcro and it's much trimmer than other reusable swim diapers that I have tried. It has lasted us through 2 children! I will agree that the fabric faded very quickly, but that did not affect its performance.

So cute... I want a top, too!

Adorable prints! So adorable, I want a top, too. The small-size cover fits my 12.5 lb daughter perfectly. My only complaint is that there are no laundry tabs for the hook-loop fasteners.

I bought bubbles in large for my 27Ib 2 year old girl and turtles in large for my 18Ib 8month old baby boy. Absolutely love these! My daughter messed hers, but a quick spray with the hose and it was spotless again(they dried within half an hour on the line as well)! No redness or chaffing and they were in them for a good 2 hours atleast, wet AND dry! Thanks bummis! Big fan!

Saved the swim day!

As my daughter at 4 months old was too small for disposable swim diapers (she could have worn one as a bathing suit if I'd cut arm holes into one), I searched the internet for alternatives. I came across the swimmi and decided to give it a try. It fit her nicely and at 8 months old, it still fits! Love, love, love the product! Swimmis allowed my tiny girl to have her 1st trip to the pool. Thank you!

Love it!!

I saw this product before my baby was even born and I knew I had to have it and put it on my registry!! My baby is almost 6 months old and we have the medium size and I absolutely LOVE it!! I love the fact that it doesn't swell up with water and it fits so nicely under my son's swim suit! He was very comfortable in it and I have recommended it to many other moms in our mommy baby group and have written about it in my blog (I loved it that much!) Thanks for offering this great option!!

We bought these for our 3 month old son when we went to Mexico. Knowing that he would not be able to spend too much time in the water and in the sun, I cringed at buying the disposable diapers and wasting 3 per day for 5-10 min swims. My friend suggested these and we bought it. Our son is a little peanut and just hit 10 months and 16 pounds. We have been using this swim diaper for 7 months and we absolutely love it! We are finally at the point to move to a medium and we will be getting the next size for sure. I am done with the disposable ones! AND I can give the little one away as a hand me down. WIN WIN!

Thank you Bummis

I bought 3 of these with my fingers crossed that they would fit my 18 month old, approx. 34 inch tall, 27.5lb son. He has generously sized thighs, not huge but he has a few baby rolls left that make finding a good fit without red marks a bit of a challenge. I have to say I am in love and impressed with these swim diapers. We have not actually worn them yet only tried on and worn around the house, but they are an AWESOME fit! Way to go Bummis!
