Aircon Underwear cool naturally
Patented design for men's hormone and sperm
What it does
Problem of men's underwear:Boxers can be bad, especially for sports, due to loose fitting leading to chafing. Briefs and boxer briefs provide support and tight up. However, they are restrictive and don’t allow body heat to escape–‘Heat can reduce sperm count and testosterone production‘ University of Wisconsin. Solution: Aircon Underwear is from boxer briefs for support while applying “chimney effect” through the right and left creases of the groin and the wearer’s buttock to cool naturally.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
