The uniforms are 26 percent lighter than their traditional counterparts, which Adidas said its research revealed was most important to players. They come with the ever-popular moisture-absorbing feature. The sleeves are made with stretch fabric that wraps 360 degrees around the shoulder to ensure full range of motion, because anyone who has played basketball knows how a T-shirt's sleeve can interfere with a jumper.

以上是addidas的說法 更乾爽 更輕 能夠增加球員表現.... 延展布料360度包覆肩膀不會對投籃造成困擾...
話說之前NBA也傳過說要在球衣上繡廣告... 這樣是否是代表未來可以貼廣告的地方更多??
