They have a straight leg cut so you can wear sneakers, work boots or dress shoes. The grey variation has a washed out look to it, the black is dark as midnight, and the blue is the popular blue jean colour we all know. They have a small logo on the back pocket and a logo patch on the back waist.

Jean Sizing Info (*not the same as a waist measurement) 

The GASP Flex Denim Size Medium is a 30 in standard jean sizing, Large is a 32 jean, XL is a 34 jean and 2XL is a 36 jean. If you have a pair of denim that fits you well and they are “jean sized” by standard then choose your regular jean size. Do not confuse or interchange a jean sizing with a waist measurement and vice versa, THESE ARE NOT THE SAME and you will order the wrong size. We have been sizing these denim jeans for over a decade and would rather you be satisfied on the first try with the correct size for your measurements.

    Sizing is perfect, and these are the best jeans out there. I’ve replaced all the others with these. The colours are ideal for semi-formal or casual wear. So comfortable!

    My favorite pair of jeans. They are stretchy and look great in any occasion. Would recommend these to guys with bigger legs. I wish Gasp would make some casual shorts too!

    Comfortable is an Understatement

    These jeans just became my favourite pair as the description is right on. Soft with the right amount of stretch lets me wear them all day at work in total comfort. I almost never want to take them off.
