LSA-709 presents a rounder version of the beloved LSA 708 frame. Crafted with the same high-quality. lightweight nylon-based TR90 frame and temples. this sun frame features a custom anti-walk hinge pin and open/close assisted detent feature for a secure and comfortable fit. The sculpted flex-fitting temples with square hole detail provided added style and functionality that is ideal for a performance cord. Like the LSA 708. the LSA 709 is emblematic of tried and true elevated eyewear design and crafted for an active lifestyle.
