Hi, Great question. All Blast Zone Commercial Inflatables are 100% commercial vinyl. Blast Zone manufactures 2 grades of inflatables: Home Use and Commercial Grade, showcased on BlastZone.com and BlastZoneCommercial.com For an in-depth explanation of the differences between the 2 lines, please check out THIS ARTICLE. We launched BlastZoneCommercial.com to specifically serve the needs of the commercial market, showcasing only the commercial-grade products, while BlastZone.com carries both grades. THIS BLOG POST takes a detailed look at what materials go into each component. All Blast Zone products are CPSC and ASTM compliant, contaminant free, and are backed by the Blast Zone promise, and real US-based support. We are aware that a number of lower grade products are showing up on the market claiming to be "commercial grade," while the non structural components are nylon. These products are essentially the same specifications as our Home-Use products. In fact, a number of these imitations use 7-oz vinyl, while our home use products use the thicker, commercial vinyl on the impact surfaces. Please let us know if we can be of further assistance. Sincerely, Blast Zone Support
