I love this product so much that I ordered another one from a promo was available! With the coat the size is perfect in M, reflecting well at night with a phone flash. Yellow reflection according to the light on it! Super quality, I recommend totally! I'm really in love with this harness! I will wait for promos to take a black and a Brown later when I have the means The reflections depend on the lighting (with the flash and the sun but also depending on the lighting of the bulb).
