I prefer to wear sweaters made of acrylic, nylon, and/or polyester, maybe a little wool blended. These sweaters by Southpole are made of acrylic and fit very well on my long, slender torso; I never feel like I have to pull them down due to length.  They don't itch like wool sweaters and look more grown-up than the polar fleece that everyone seems to wear all the time now.  I wear these to work and on the weekends.  Also, I like that they don't have the brand's logo printed all over them.  Just a nice, understated logo on the left breast, occasionally.  Quality control is an issue though, which is why I didn't give a 5.  You really have to inspect the items for fraying, holes, and bad sewing.  But I'm more than willing to do that for what I get when I do get a good product.  And Amazon makes returns and reordering easy!
