Asterisk Introduces the UltraCell™ Knee Protection System

October 24, 2011 12:00pm

Lake Forest, CA - Asterisk is pleased to announce the introduction of the UltraCell™ Knee Protection System. The UltraCell™ is built on 10+ years of time-tested and proven designs of the original Cell® Knee Protection System. Those original concepts have been refined, improved, and entirely reengineered to create the UltraCell™. The UltraCell™ is, as its predecessor, completely customizable to the leg while remaining extremely rigid.

Asterisk is also proud to announce a brand partnership with Boa® Technology. The award-winning Boa® Closure System is, in our opinion, simply the best system available today. Boa® Technology has a ten-year, proven track record in a variety of action sports and other industries.  With their simple, yet powerfully effective method of closure, it was a natural fit to use the Boa® reels and closure components on our Dual-Independent Securement System. Securing the UltraCell™ to the leg has never been easier.

The features and benefits are too many to list, but can be found at

The UltraCell™ is distributed exclusively through WPS and can be purchased through an Asterisk authorized dealership, as well as online directly at



The Ultra Cell™ Knee Protection System is without question the most technologically-advanced Knee Protection System available. Several patented revolutionary design concepts come together in unison to create this System. The A.R.C. Cuff's ability to be totally adjustable for fit, yet remain rigid, along with a superior fastening design in partnership with Boa® Technologies, a natural free-motion, rolling-gliding hinge, tibial plateau-capturing frame design, brace-to-boot tether attachment, and a full time-full coverage patella cup, sets this knee brace decades ahead of all the rest.
