Its hard to push a double stroller and hold an umbrella so i have been searching for a good raincoat to keep me dry

I would advise you go up a size since it does run a little small

This raincoat is perfect its light weight so you can layer up underneath it has an adjustable bungee hood and waist reflective striping down the front and across the back and pockets that zipper shut

Generally a medium i always go up one size up in jacketscoats for a more comfortable fit
