The Oakley Splice is basically built on the same chassis that the Crowbar is. It should fit similar to the Crowbar. It has additional downward peripheral and zero pinch around the nose which leads to better nasal air flow.
The optics on the Crowbar can't be beat, so why change? Want something different? Check out the new Oakley Splice. Same optics, increased downward/outward peripheral, and no nose pinch so better nasal air flow.
