The Union Ultra is basically the “why does this feel so good?” binding in Union’s line. It’s a mid-flex, super-comfortable, ride-anything binding that’s perfect for park laps, side hits, cruising the resort and generally messing about on the mountain.
It gives you loads of board feel, a smooth, cushioned ride and just enough response to crank turns without feeling stiff or twitchy. If you like your bindings lively, playful and ridiculously comfy straight out of the box, the Ultra is absolutely in your lane.

Final Thoughts - Should You Buy It?
If you want one binding that makes your board feel more fun and more comfortable, the Union Ultra is a gem. It’s lively, forgiving, and just responsive enough for most riders who spend their time popping off side hits, cruising laps with friends and dipping into the park. It’s not built for big-mountain psychos, but for everyone else, it’s one of the most enjoyable bindings Union makes. At Wobble, we rate it highly because it suits the way real people actually ride - relaxed, playful, all-mountain snowboarding with a big grin on your face.
