DITA’S collaboration with Boris Bidjan Saberi re-interprets the traditional mountaineering frame with design and manufacturing innovations that combine raw titanium with advanced optical engineering. Designed with functionality and craft in mind, the frame’s minimalist appearance draws upon the engineering of an innovative titanium unibody frame. Manufactured by some of Japan’s oldest and most respected craftsmen, the frame is engineered with a single piece of titanium instead of two separate halves joined with a visible seam.
This unbroken titanium structure utilizes a tension-based rimlock system to secure the lenses, representing a dramatic evolution in traditional optical construction. The hingeless frame system integrates retractable cable temples into the design of the titanium side cups. Two small hooks interlock with the side cups and provide a pivoting point, which is unusual for a frame of this style.
