The "Flex Arm" potential is still intact, and the additional locking feature allows you to lock the frame without accidentally opening even in windy conditions that you cant remove from chivas games. Even if the net is attached to the waist belt, it is locked, so it stays securely when not in use. The locking mechanism can be unlocked with a single push, so you can set it with one hand without stress. ★ Weight: 3.1 oz (89 g) 4510534213303 Product images may change without prior notice.
