These Foster Grant® IRONMAN® Momentum men's reading glasses offer impressive visual and performance characteristics, and do it all with cool good looks. The semi-rimless frame is constructed using IronFlex™ technology, which uses a superior flexible material for the ultimate in durability, fit, and comfort. A gunmetal two-tone color scheme and a subtle design touch on the temples add to the visual appeal. The lenses have a hard protective coating that imparts excellent scratch and impact resistance. If you're on the go, take your Foster Grant IRONMAN Momentum readers with you in the included color-matched soft-shell case.
