Interview: Freestyle Diapers Founder on Disrupting Baby Care With Clean, High-Performance Products
Freestyle Diapers are clean, high-performing, and nearly half the price of luxury brands.
We sat down with Mike Constantiner, co-founder of Freestyle Diapers and the first dad to appear on Whole Bunch Club, to talk about diaper safety, sustainability, and why clean products shouldn’t have to cost a fortune.
From Tech Entrepreneur to Diaper Disruptor
With a successful career as a tech entrepreneur, Mike didn’t set out to start a diaper company. “Freestyle started because my co-founder and I, both dads, were talking about how behind the category was,” Mike shared. “Legacy brands felt stuck in the past, and the newer ones were either too expensive or didn’t perform.”
So they built something better: a diaper brand that’s truly clean, built for performance, at an unbeatable price.
“Legacy brands felt stuck in the past, and the newer ones were either too expensive or didn’t perform.”
What Makes a Diaper “Non-Toxic”?
The phrase non-toxic gets thrown around a lot—but Freestyle backs it up with science.
“Non-toxic to us means full transparency: clear material sourcing, lab testing for chemicals, and certifications that hold weight.”
Freestyle is:
EWG Verified (only the third diaper brand ever to receive it)
OEKO-TEX Standard 100 certified
Made with FSC-certified tree pulp
Independently lab-tested for PFAS, phthalates, and BPA (with results published)
Even their top sheet—which uses a polyethylene/polypropylene blend often misunderstood in clean-living circles—is tested and verified safe. As Mike put it: “It’s not about whether a material is synthetic. It’s about how it’s processed. We independently test for contaminants and share the results.”
High Performance, Without the High Price
One of the most surprising things about Freestyle is the price. You get a premium product for the price of Pampers!
Their secret? Smart product engineering.
“The innovation in our Skin Shield Diaper’s core allowed us to use fewer materials without sacrificing performance,” Mike explained. “That let us bring the price down to match—or beat—mainstream brands.”
The result? A top-tier diaper that is verifiably safe, holds up overnight, and costs half the price of comparable luxury brands.
Mike’s Favorite Non-Freestyle Product
Mike swears by VanMan’s tallow balm—a super simple, all-natural skin salve with just a few ingredients. “It’s very inspiring to try to figure out how to develop products with that level of simplicity.”
