How does the relaxed fit compare with Wrangler's regular cargo pants?

It is cut looser through the hip and leg than a regular-fit cargo, so expect more room and a straighter, baggier line. If you normally size down in relaxed fits, consider it here.

What are the trousers made of?

A cotton blend, which gives some durability and breathability without the stiffness of all-cotton canvas. It is not described as stretch fabric.

Are the cargo pockets big enough for a phone?

They are full side cargo pockets with flaps, sized like typical utility pockets, so a phone fits but will sit low on the thigh. The flap keeps contents covered.

Can these be worn for work?

Yes for light work and casual jobsite use. They are not reinforced or heavy canvas, so hard abrasion and heavy tool loads are better served by dedicated work pants.

How should I wash them?

Machine wash cold and line dry or tumble low to limit shrinkage and fading on the cotton blend. Avoid high heat, which stresses the blend and the black dye.
