A sensory activity sack provides a garment with pleasant tactile features offering safe sensory stimulation for persons with developmental or sensory disabilities and an isolation bag for the wearer's arms and hands. The isolation bag prevents the wearer from engaging in self-injurious behavior or other harmful behaviors. Multiple fabrics and textures in the isolation bag, including mesh and denim, provide a pleasing tactile experience, which can be furthered by the placement of toys into the isolation bag. Sensory panels made with a sturdy, textured material such as denim provide tactile stimulation and resistance against wear and biting, as well as adding a comforting weight to the sensory activity sack for wearers with sensory issues.
