GLOSSARY: TSM 4-way stretch shell fabric (Thermal Sensitive Memory) E+O's laminated shell fabric repels water and wind thanks to its DWR (Durable Water Repellent) finish. It is exceptionally breathable and draws moisture and heat away from your body and out through the shell. The lamination automatically reacts to changes in temperature triggering TSM to boost water resistance or breathability. The 4-way stretch promotes greater freedom of movement.
