Suggestions for a hard, portable mousepad for my alienware laptop?

I just got the razer orochi gaming mouse for my alienware m11x and am loving it but i am now realizing im going to need a mousepad.
Was wondering if anyone could suggest a hard, fairly portable mousepad i could look into

Thought i should add - im looking for a hard mat because i usually use the laptop on places like my bed on which obviously a soft mat wouldn't work

Thanks
