My granddaughter lives in Columbia Fleece jackets during the school year.  She has a number of them because they are comfortable, very wash-&-wearable, they easily stuff into a backpack, and they come in a variety of colors.  Because her classroom is warm, she prefers to wear shirts and layer with the fleece rather than wearing a sweater she cannot take off.  It keeps her warm enough that she does not need a heavier jacket on most days.  We live in Northern California where the winter temps are usually in the high 50's to low 60's. Columbia makes a high quality product and it has the added bonus of lots of pockets, oh-so-soft fabric, and great colors.  They run true to size, so order what you normally buy.
