Klim Aggressor 2.0 Shirt

Klim’s mid-weight base layer piece is engineered with mechanical fabric construction in main body for aggressive uptake of moisture from the skin and rapid transport to the fabric’s outer surface. The Aggressor 2.0 shirt utilizes Thermal Mapping technology with Level 1 fabric in high-heat producing zones and those prone to bunching such as the armpits, collar and  lower back.


  • Mechanical fabric construction accelerates moisture transfer from skin to mid-layers/outerwear
  • Thermal Mapping technology incorporates Level 1 fabric in high heat and mobility zones
  • Smooth surface for bunch-free fit under fleeces and outerwear
  • Low-profile flat-lock seams
  • Enhances breathability and comfort of Klim outerwear systems
