The Haida Anti‑Fog Belt is a lens heating accessory designed to prevent condensation and fogging on camera lenses and telescopes by gently warming the optical surface. Powered via USB, it maintains a temperature above the dew point to help preserve clarity in humid, cold, or temperature‑changing environments.

Equipped with multiple heat settings and a flexible attachment system, this belt supports use in field photography, night shoots, and extended outdoor sessions where lens fogging could otherwise degrade image quality.
