Bouldering T-Shirt

Giving your kids a piggyback ride takes physical effort—so wouldn't it be easier if they just climbed up on their own?

The "Bouldering T-Shirt" is wearable gear with colorful climbing holds bolted onto the back, essentially transforming a parent's body into a miniature climbing wall. As the child scrambles up the grips for fun, they naturally end up in a piggyback position.

Beneath the T-shirt and jeans runs an internal sling vest rated for up to 4 tons of load capacity, which securely anchors the climbing holds in place.

As a peaceful, win-win parenting hack where the parent just stands there, the kid enjoys a climbing route, and both end up piggybacking, it gained wide attention on Twitter and was featured on Japanese morning TV shows, including Nippon TV's ZIP!.
