A collapsible canopy apparatus is provided. The apparatus includes a canopy mounted onto a collapsible frame. The frame includes flexible and resilient spring members that are biased in an upright position. The spring members include arcuate regions that define the arcuate shape of the frame. The spring members are interconnected at flex points that enable the spring members to fold relative to one another by twisting and bending actions. These actions enable a user to collapse the frame into a folded, storable configuration. A harness disposed in an interior of the canopy includes a waistband and shoulder straps for enabling a user to fasten the canopy to his or her torso and suspend the canopy therefrom. The shoulder straps include fasteners configured to removably attach to the interior of the canopy. Slide ribs disposed on an interior of the canopy enable vertical adjustment of the waistband.
