How do Mitchell and Ness football jerseys fit? Any Insight?

[luis-m16]

Im about to order a football jersey and they have a sizing chart, but I'm a little unsure of what size to order as I usually dont buy jerseys

I'm stuck between Small and a Medium, I'm about 5'6 and 160 pounds


Anybody have any experience with Mitchell and Ness football jerseys? Do they run small or big?

Thanks
