I went by a Sears store today to get a a hands on with some of the Lands End fleece tops they have on sale. I picked up a crew neck top for $12 and it weighs a paltry 7.8oz in a mens large.
This will make a good summer mid layer teamed up with a windshirt.

They have a nice 1/2 zip top for $17, but I went for the utter simplicty and lower weight of the crew neck v
They have all kinds of tops, 200w jacket, gloves and beanies at steep discounts.
