Callaway have been known to produce top notch clothing for a while now. They make great looking gear that incorporates state of the art tech to make sure each garment does exactly what it should do and more. The long sleeve 1/4 zip is ideal all year round, being warm enough to wear over a t shirt in chilly summer mornings, but thin enough to go under an outer layer without restricting movement. The sweater is really soft to the touch, making it comfortable for all day use. The top has thermal properties which will help to keep you warm whatever the weather and its spandex/polyester mix gives you a lot more movement than more static materials provide.
