5.11 Tactical's Utili-T undershirts are extra long to stay tucked in all day and are tapered for a clean fit. Each is constructed of 4.5-ounce, ringspun 100-percent cotton jersey enhanced by nano moisture-wicking technology. 5.11 Utili-Ts don't build static electricity or melt like synthetic shirts can when exposed to flames. Available in both crew and v-neck styles, the shirts feature a 1-inch, no-roll, high-density collar for a cleaner, more professional appearance, plus double-needle tailoring at the neck and shoulder and a stamped label that won't irritate your neck. Available in white, ACU tan, dark navy and black, Utili-Ts come in a convenient three-pack.
