This is my spare Altura Esker "smock". I wear a large and got this to return, ended up not...and here we are :-) Its brand new, never worn and all the tags are still on, do your research, but these are a great lightweight waterproof top layer. There is a pocket on the front and a zip on the side to let you cool down when it gets a bit hot in there! Grab a bargain, any questions, please ask :-)
