A house note

On the art of the quiet fighter.

— with our regards,

The Henderson Workroom

“A well-made mitt will outlast a bad decision. A speed bag with honest leather will outlast the trend that replaced it.”

Henderson Boxing opened its doors in 2025, but the game we answer to is a great deal older. We take our cues from the old workrooms — the ones that built a mitt to be repaired, not replaced, and knew a speed bag by the sound it made.

Every piece is full-grain leather, hand-finished, and cut to a standard we borrowed from a better era. New house, old rules — no shortcuts, no plastic, no apologies.

The OS-1 mitts broke in like a favorite pair of boots. Padding holds up round after round — no dead spots, no seams giving way.

Speed bag sounds like an old gym should. Leather is honest, rivets are tight, and the rebound is exactly where you want it.

I train out of my garage. The double-end ball earned its keep in a week. Feels like gear built by someone who actually hits the bag.
