Summer is almost upon us! For my family that means seeking out water to stay cool on these ever increasingly hot days. Luckily, there’s no shortage of lakes, rivers, and beaches in my northwest neck of the woods. But with an adventurous toddler, I prefer the safety and fun of spray parks and splash pads these days. We’re lucky enough to have one less than 10 minutes away in our city plaza, so when Bummis sent us the new one-size Swimmi, an adjustable and reusable swim diaper, I knew a visit was in our near future.
It was the perfect kickoff to a summer full of water fun, and, biased though I may be, he was definitely the cutest kid there in his Starfish Swimmi one-size.
Anatomy of a One-Size Swimmi
This swim diaper has four rise settings and three waist and hip snaps on either side. The snaps on the new Bummis diapers are definitely worth mention. They’re sturdy, easy to fasten, and look like they’ll hold up to regular use for many years. The Swimmi has double gussets to prevent leaks—very important in public swim areas!—and the leg and back elastic is really strong. The fabric inside is soft and breathable, and their laminated lycra is a unique fabric that resists fading.
Fit and Performance
The splash park technically wasn’t this diaper’s maiden voyage. We tried it out at home first in our kiddie pool, but there was a lot of sagging fabric in the back. I sent Olivia some pictures and asked, “What am I doing wrong here?!” She let me know that swim diapers should fit pretty snug, almost like a pair of underwear. My mistake was adjusting the size to fit like a regular diaper cover which makes room for a prefold or soaker. I reset it all the way to the smallest rise for Brooks, and that was perfect for him.
The Swimmi one-size claims to fit babies 10 to 35 pounds, but every kid is different. Brooks is 23 pounds right now, and after trying this diaper, I think it would be a more ideal fit for babies in a higher weight percentile so their legs and torso fill things out better. Brooks is on the slender side, so I’m not sure how well the Swimmi would have worked for him last summer, even though he was still within the recommended weight range.
As for performance, it worked exactly the way a good swim diaper should. Just like a disposable swim diaper, they are not designed to absorb pee but simply to catch solids. And with the strong elastics and double leg gussets, I definitely trust the Swimmi to keep community water sources clean.
Brooks threw a classic toddler tantrum when we had to leave the spray park. I consider that a compliment to the fun we had, so it looks like we’ll be going back again soon. Our Swimmi will get tons of use this summer, and the quality and flexibility in sizing means it should work for our family all the way through potty training. Brooks didn’t dirty his while playing, but I’d recommend getting a couple of them for each child so you have a clean one to put on if they do go potty.
The Swimmi one-size is $26 from my local retailer. That beats buying expensive packs of disposable swim diapers that just go in the trash after an hour or two of playing, and, because Bummis manufactures all their diapers in Canada from fabrics sourced in North America, you know that everyone who played a part in the fabrication of each product was paid a fair wage. You’re getting a fantastic diaper and supporting a strong local textile industry.
