Windbreaker material. I can't stand it. That and sheets, umbrellas, loose clothing, coat linings, and those 3d sports cups. The most dreadful sensory obstacle is washing my hands. After I wash my hands, everything I touch gives me goosebumps, especially paper, my laptop mouse, clothing, and the drying towel.
The only things that I feel comfortable touching are soft, fuzzy jackets, socks, slippers, blankets, robes and dogs.
