Chiaro Biking Onesie

Meet Chiaro’s first biking onesie, designed for those who value simplicity, style, and functionality. The fit is inspired by shapewear for a sleek silhouette, yet offers the flexibility you need to move (crafted with 80% recycled nylon and 20% spandex).

Made for warmer rides in spring and summer (18–35°C). Fill the pockets, toss on a sweater, clip in or don’t, ride 5km or 60—we’re just happy you're moving.

If you're between sizes, size up. Cold wash only. Hang to dry. 

Canada only. Shipping on us.

We do not accept returns, but we’re happy to offer exchanges for new sizing as long as the product is unused and in its original condition. Please note that buyers are responsible for the shipping costs associated with exchanges.

I’m in between sizes—should I size up?
Yes! If you’re between sizes, we recommend sizing up. Our fabric is compressive and designed to hug your body, so going up one size will give you a more comfortable fit.

Can I wear the onesie for a triathlon?
On paper, the Chiaro Biking Onesie is made from very similar fabrics to what you’d find in many triathlon suits (80% nylon and 20% spandex). That means it’s breathable, stretchy, and quick-drying. The main difference is in the bum padding: our onesie is designed specifically for cycling, the chammy isn’t the thinner, quick-dry style you’ll usually see in triathlon suits. After the swim, it may hold a bit more water and feel noticeable.

Can I wear it without a sports bra?
The Onesie is designed with enough stretch and coverage to wear either with or without a sports bra, depending on your preferences.

Is it machine washable?
Yes — just wash cold and hang to dry. Avoid the dryer to preserve fabric stretch and longevity.
