Nike windbreaker – mesh back lining under “open” flap back

Nike windbreaker – mesh back lining under “open” flap back – size M – 25” pit to pit – length 26” – sleeve: raglan 31” from neck – hem elastic 19” to 24” – it doesn’t seem to show in the pictures, but the sleeve inserts have yellowed - otherwise excellent condition - very lightweight Because sizing - even online size charts - is all over the place, I have sized as close to an average as I could, but included all measurements in the description.
