I really like rain coats.
What about the Apex Flex Jacket from north face, its waterproof and breathable 
That sounds great! I love breathable jackets.
Do you like any other brands besides North Face?
I like the arizona brand of rain coats.
do you like medium, large or x large rain coat
I like large ones.
is $7.40 USD a fair price for a large rain coat?
I think that is more than a fair price!
