After work, close the zip pocket to protect small valuables and follow garment care instructions on the label to maintain fabric performance and reinforcements.

Usage recommendations

For prolonged durability, avoid contact with sharp abrasive surfaces whenever possible, use knee protectors for intensive kneeling tasks, and wash according to the care label to preserve the stretch inserts and reflective elements. Inspect reinforced areas and seams regularly and repair promptly if wear appears.
