X-Static® - The Silver Fiber™
X-STATIC® fibers are permanently bonded with a layer of 99.9% pure metallic silver. This silver layer is the key to X-STATIC®'s powerful antimicrobial properties, as it creates an ionic shield that permanently inhibits the growth of bacteria and fungi while enhancing thermodynamic, and anti-odor properties.
I-beam construction eliminates welded seams to reduce cold spots and ensures quick inflation/deflation, consistent air flow and stability.
