ALL-NEW Carbon Cell 1 (CC1). The CC1 is manufactured from Military Spec and Aerospace grade carbon fiber prepreg that is made in America, the finest in the world. Our focus during the design and development of the CC1 was making the slimmest, lightest, most comfortable knee brace in the world. We wanted a brace that fit so well on your leg, it looks like it's painted on, and we hit a home run! At roughly 1lb or 454g (+/-depending on size) per brace, we believe it's the lightest, best fitting and most comfortable functional knee brace in the world, without sacrificing strength and durability. The CC1 is backed up by a 3-year frame warranty. Asterisk is the inventor of the off the shelf carbon fiber performance knee brace, and in the world of knee protection and bracing, this is a game changer. Undersleeves and Tethers are included.
