My mom would've been sad if I hadn't worn the new one and no one hurts mama. There is a small blemish near the chest straps (last photo). I didn't carry any heavy items in the vest, so the pockets are still elastic and the closure systems are not stretched out or worn. The pockets are in good condition and the velcro functions as it should. All in all, it's great for all levels and can be used as a primary or a backup!
