Here is more from NikeInc.com on the uniforms:
-- Nike Flywire reinforces the neck area while providing a closer fit to prevent slipping. The aesthetic also provides a nod to the traditional lace neck design. -- Reduced seaming eliminates weight and creates a more traditional blocked look. -- Recycled polyester embraces sustainable innovation without compromising performance. Each jersey is made from about seventeen plastic bottles and the socks use --- approximately five plastic bottles. -- Lightweight premium letters and numbers shave off unnecessary weight. -- Zoned ventilation and articulated sleeves for ventilation and maximum range of motion. -- Stretch open hole mesh under arm for added ventilation.
