The new EXO III are the most expensive of the top contenders, at $175, and have the most elaborate system for delivering support to specific muscle groups. Salomon also holds a patent for the compression technology, which it describes as a stretchy grid-like “film laminate” that goes over the tights in certain regions to provide better alignment on trail runs. You can see this grid as a design feature on the outside. Right now the full-length EXO III model is designed only for men, with a 3/4-length EXO III for women.
