My joint item is Black Yak Body Gear BBG knee protector.

For someone who loves mountains, Black Yak Body Gear BBG knee brace has become an essential item. As I get older, climbing mountains is less difficult, but descending makes my knees uncomfortable, so I started wearing a brace, and it definitely helps my knee joints. It's easy to carry, so it has become a must-have item even when hiking in the back mountains today.
