I bought this to replace my previous Roost Pak which lasted about 7 years. I've used the pack with a Fox Aiframe and a Leatt Pro 5.5. The pack attaches easily and securely to both chest protectors. The pack has several well-designed pockets for easy access to frequently used items (phone, money, keys, glasses, snacks...).
