Callaway are known for producing top-notch clothing. 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 Odyssey 1/4 zip Sweater is ideal all year round, being warm enough to wear over a t-shirt on 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.
