As these Summer nights (hopefully) begin to cool down, it's always a good idea to have a few long-sleeve zip-ups on hand. We're going with this Puma Form Stripe Jacket ($85) to keep us warm and bug bite free. It features a nice contrast stripe on the right side with a white stripe across the top and comes in a comfortable 55/45 polyester and cotton blend. Sure, it's really made for working out — but when has that stopped us before?
