Thank you for viewing. This is an arm guard (elbow) for lacrosse. The lower strap (the part that the band hooks onto) on the left arm is detached. It can be worn by hooking the lower band onto the upper strap. (Image 3 is a wearing example) As you can see, it has been used quite a bit, so please purchase it if you understand this, such as if you urgently need an arm guard. - Brand: Warrior - Color: Black
