A little too bulky for me but does protect the case. 70 oz. If you find the XM3s tight the extra padding may make it worse untill they flatten with use. Very glad purchased via Amazon, the return process was smooth and painless. But, while the styling has continued to evolve and improve, another long-standing feature Rockport maintains is that "right out of the box fit" nature. I would not recommend using the straps that come with this hitch by themselves. This VEEYOO 2 tier spice rack is very handy. They are a nice looking shoe but they are def not a size 8, very narrow and my dad couldn?t get close to putting his foot into shoe. So tight I couldnt even get it on. The size chart for my measured feet suggested a size 9.
