Adidas SST pants

Picked these up because I’d never seen anything like them before. The material is more protective than the normal adidas track pants. Pic 4 gives the best idea of the material. The tag says size small. All of my adidas pants are size L. This pair fits as a size L would. Do not expect them to fit as a Small. Typical size S would drown in these pants. Rare find, cool pants. Can be worn In any season but summer.
