The Assessor 2.0 with improved outer-fabric was built for the prepared professional who needs to comfortably conceal firearms or gear without the tell of an undershirt. The hidden, semi-compression layer prevents gear from chafing skin and includes VaporCore, powered by 37.5 Technology, which actively keeps you cool and dry no matter what the mission is or where it takes you. The outer-fabric is composed of poly/cotton blend.
