The SP-J4 is a full specification aramid reinforced motorcycle riding cargo pant.
Yes they look good, but here's why they're technically better:
The yellow stuff is Aramid. It's one of those miracle materials. Only 100% Aramid is used on SP-J jeans. Anything else is a cheap mix which won't have the same protective properties. Avoid it, it's a waste of money.
Aramid panels are generously sculpted to the shape of the jean and stitched into a triple seam at the sides- this is the most likely point of impact.
Soft mesh pockets hold CE EN 1621-1 armour in place while allowing your skin to breathe
Proper heavy duty fly zips are used, not fiddly buttons!
Large, strong belt loops are featured for durability in a harsh environment
Large aperture pockets are much better suited to motorcycling than fiddly small ones
