He came to California for a visit and stopped in San Francisco to meet us. As you would expect, RubNGum had a lot of gear with him including a new ultra-heavy 4mm straitjacket and sleepsack. During the last year I have started to see guys buying ultra-heavy gear like this from various manufactures around the world. RubNGum's 4mm straitjacket and sleepsack are available on his website, and I imagine he will have other new and exciting 4mm gear to offer in the future.

RubNGum is one of us. He's a gear head. He loves to collect unique and unusual BDSM gear. He's also into the color black. That's why is retail website is called He also has a video website at, and as you will see, black rubber is the driving theme. I guess he likes the starkness of black gear. So do I, however, RubNGum has taken his attraction to the color black to the next level by owning an all-black electric toothbrush! Yep! I didn't know that black electric toothbrushes were even available. I don't think he spray painted it either, I think he bought it that color. This guy is the real deal!

Anyway, RubNGum flew into Los Angeles first to visit some friends. His plan was to drive up the California coast to San Francisco, so I suggested we meet up at EdgeDungeon which was along his way. Sure enough, his rental car was full of suitcases filled with gear. We decided to shoot a video showing us all of his gear. That video is coming in the future. For now, the video in this update shows RubNGum in his 4mm ultra-heavy straitjacket. If you look closely, you will see that the straitjacket arms have built in pre-bent elbows. This is required because the rubber is so thick that the crease that develops in the rubber where the elbow turns would cut off your circulation. This is a great idea and allows you to comfortably wear the straitjacket for a long time.
