What's the inflatable made of?  

Quality urethane. This is the same high-performance material used to make top-of-the-line hydration packs like CamelBak! Bonk Fit is PVC-free and built-to-last.     

Is assembly easy? 

Super-easy. Weight base; four (4) pounds required, we recommend play-sand, kitty litter, or uncooked rice. Inflate; use basic pump or hearty set of lungs. Slip-on skin.

How durable is it?  

Super-durable. It's 3X tougher than other punching bags. Bonk Fit™ has been observed in a series of stress tests, including a seam test and inflatable burst test by a 3rd party lab, accredited by the CPSC. In the seam test, technicians applied 15 pounds of force to within 1″ of the seam, for a period of 10 seconds without failure. In the burst test, technicians slowly pressurized Bonk Fit™ with air until failure was observed at 2.0psig and 1.65psig. When filled with water and dropped from an elevation of greater than two feet, Bonk Fit™ is highly likely to burst. Don't do that.

Do you sell internationally?  

Yes. At checkout, you need to use either an Amazon or PayPal account to complete your purchase. For shipping to Canada and the UK, select the Flat Rate option. If further assistance is required, reach us using live chat or email us at

Is the skin machine-washable?  

Yes! Toss it in with your laundry. The fabric skin is pre-shrunk so no worries about drying it on high.
