I am thinking of some warmers to take on my tour. I am a chunky monkey kinda girl! How do I figure out what size to order? I am only 5'4 but since I am heavy, I wear XL or XXL usually. Are they that stretchy that I am over thinking this?!!

I just moved so I am broke broke broke. I want the bolero, but I must make concessions.

While I am at it, should I invest in a helmet cover? Are they super hot? Michigan weather is so unpredictable that I can't tell you if it will be 75 and rainy or 50 and rainy!
