The resilient, battle-hardened CDI™ sunglass has a long track record of saving eyes and lives in hostile situations. Following a series of comprehensive overhauls, the redesigned CDI™ has never been better. The ESS CDI's U.S. MIL SPEC* high-impact lenses can be easily exchanged for quick adaptation to your environment.
Its high-speed low-drag frame and shatter-resistant lenses make the CDI™ comfortable and cool enough for downtime yet functional and rugged enough for the battlefield.  Medium fit.

New Improvements Include:

• New cam-hinge temples feature SmartTension™ engineering for enhanced retention and a more comfortable fit. 
• New co-molded nosepiece and full-wrap temple sleeves feature advanced no-slip rubber that provides maximum slip resistance, even when moist.
• Redesigned strap attachment system provides more secure engagement of strap and frame.
• Now includes a zippered hard case and a micro-fiber pouch/cleaning cloth.

CDI Kit Includes: A Black CDI frame, two sets of 2.2mm high-impact lenses (Clear and Smoke Gray), an elastic retention strap, a micro-fiber pouch/cleaning cloth, and a zippered hard case.

CDI Rx Inserts are also available.

* Mil Spec MIL-PRF-31013 (Clause 3.5.1.1), ANSI Z87.1-2010, CE EN 166 and U.S. Federal OSHA compliant (when not used in conjunction with Rx Inserts).  All ESS lenses provide 100% UVA/UVB protection.
