Guys, if you wear these with anything other than work pants/trousers (high rise, loose fit) -
You should size up a full size, maybe even two! (skinny jeans, low rise etc).
I'm size 30 waist , using 34 belt for jeans and 32 for trousers.
If you're in-between sizes, or unsure whether you got the measurements right - ALWAYS size up, NEVER order the exact same size as measured - unless you already own an Orion belt and know exactly what your size is.
