Amazon EssentialsMen's Sherpa-Lined Full-Zip Fleece Hoodie

The size chart seems a bit inaccurate? not sure whether to get s or m. do these come up large?

How long is the back of the XL from the base of the hood to the bottom of the hem?

any inside pockets in these hoodies?

reading few reveiw, is it really on the small side? size L here but prefer tight on me, so not sure should go for xl
