The Cadet Pro, a youth version of the bindings used by professionals, features a softer flex, making it the perfect snowboard binding for kids and young teens looking to take their snowboarding to the next level. It's comfortable, easily adjustable, and allows you to ride any terrain on the mountain. Binding Flex: 5/10 ●UNION BINDING SIZE CHART YOUTH Size MONDO (cm) 23.5 - 25.5 *Sizes are manufacturer recommendations, and may not fit depending on the type of boot, even within the recommended size range. Purchased this season, used less than 10 times. Although it's a youth line, I think it can be used by those with a light body weight. I especially felt it would be good for spring snow. Bonus: Union soft binding case This is from the Ultra a few years ago. I think it will be useful for carrying bindings and storing small items. For an additional 5000 yen, a Flux titanium screw set can be included. Please let me know. Thank you.
