SP-I, the original Sunpocket frame and a true unisex model playing with the heritage of the alps in the 1970s and 1980s. Originated in 1976 the SP-I is an ultra lightweight frame, designed with an enhanced temple-tip curve for bounce reduction combined with lenses shaped for optimized visual protection. This model turns 50 years young in 2026, making it not just a frame but an icon.
