THE 5.11 TACTICAL 3-IN-1 JACKET IS UNIQUELY ENGINEERED WITH DUAL LAYER RESISTANCE TO MOISTURE PENETRATION WHILE ALLOWING MOISTURE VAPOR INSIDE THE JACKET TO PASS THROUGH THE 100% NYLON FACE FOR MAXIMUM BREATHABILITY. IN SHORT, THIS JACKET WORKS TWICE AS HARD TO KEEP YOU DRY. COMBINE ITS WATERPROOF/BREATHABLE ABILITIES WITH A FULLY TAPED SEAM CONSTRUCTION AND YOU HAVE A TACTICAL PERFORMANCE JACKET THAT, LIKE YOU, ALWAYS GETS THE JOB DONE.
