The nylon construction has reflective tape stitched in that really lights up. It is reflective for at night. The harness stays on and is mostly well made.

Sizing is as described and quality is great. It fits perfectly.

Sizing chart was not accurate. Couldn't get the buckle done. Returned them both.

This harness fits my elderly mini dachshund (about 10 lbs) pretty well. It is fully adjustable from one end of the harness to the other.
