This jacket is lightweight as stated. I do like that for riding a bike, plus other sports...since it is Unisex I ordered a small and it is good if a lady is of a slim build.  The fabric is slightly see through, but not too much so.  The color is more of a lime green and not bright NEON.  It does look more neon since the picture shows 'yellow' underneath.  It is well made.  All in all it deserves a 5 star, for me....I do not know what the other colors are like. They appear to be of a thicker fabric.
