I relied on the previous reviewers and bought Large for my 9 year old son. It was way too large. I found out the large is for 14-16 years old. It almost fit me I am size 2-4 at 5 ft 3 inch female. The arm's length is short for me.
The raincoat is self has a mash fabric lining and it is not too thin or thick. It is a bit long. I will try to order a small size and see if that will fit better.
Dress them on even the dreariest of days with this youth new Englander rain jacket. This jacket is made with wind and waterproof new Englander polyurethane that is bonded to a woven backing to provide additional fabric strength, is lined with mesh for air-flow circulation, and taffeta nylon in the sleeves for easy on/off. It also features elastic gathering at the hood with no drawstring for added safety, heat sealed seams throughout to seal out the wind and rain, covered side pockets, and elasticized cuffs. A reflective single stripe accent at hem on front and back, plus a dual stripe accent on right arm on colors wave, aqua, coral, and hot pink.
