Nanotech Materials for Extreme Sports Gear: Any Real-World Examples?

I’m curious about how nanotechnology is actually being used in endurance gear these days. I’ve seen some lab concepts for self-healing fabrics or moisture-wicking surfaces at a molecular level, but I’m wondering what’s made it to market for activities like rock climbing or ultramarathons. Are there any brands integrating these materials into things like harnesses, shoes, or clothing in a way that genuinely improves durability or performance? I’d love to hear if anyone has tried gear that uses these advanced materials and noticed a practical difference.
