Built tough but flexible enough for easy access to your gun. I do wish it had a better way to keep back-up magazines in the gun pouch. My S&W .40 Shield fits very nicely but only had room to fit one back-up mag. Plenty of room in other pockets but I'd rather keep my gun and mags in one pouch so I have only one place to go to if hostile situation arises. I highly recommend this product over any other weapon fannypack.
