We've updated our case series names. Edge (formerly Ultra-Slim), Cairn (formerly ProGuard), and Summa (formerly UltraGuard) now reflect the experience, not just the specs. Edge: slim, light, and sharp along the climb. Cairn: firm and dependable, like stone markers that guide the way. Summa: the peak, where protection and hand-feel come together.

CLLN represents our brand philosophy: "Carry Lighter, Live Now." It embodies PITAKA's commitment to minimalist design and effortless living.

It comes down to its structural design. While both series combine TPU and aramid fiber, Cairn incorporates a unique arched structure—raised reinforcements at all four corners. In the event of a drop, this arched design effectively absorbs impact, significantly enhancing overall protection.

Cairn has passed military-grade drop certification and can withstand standard drop tests from up to 2.44 meters (8 feet). This exceptional protection is mainly attributed to the arched cushioning design at the corners, which effectively absorbs impact during falls.

Cairn focuses on ultimate drop protection: Uses hot-press molding, retaining the skin-friendly woven texture of aramid fiber for a grippy, fingerprint-resistant feel. Features an exclusive arched cushioning design for military-grade drop protection, ideal for users who prioritize safety.
Summa is the flagship model, emphasizing both protection and refined details: It utilizes 3D thermoforming technology to seamlessly integrate aramid fiber and TPU, resulting in a smoother, more premium feel that is also easy to clean. Equipped with full-metal physical buttons that cover the camera control button for more responsive operation. Upgraded with self-developed Orca Resin for a lightweight yet ultra-durable build with double the impact resistance, reflecting PITAKA's pursuit of perfect balance between protection and aesthetics.
