More About Men's Base Layers

Everything starts with your base-layer. It’s what you wear almost every day of your life, it’s your first shield against the elements, and it’s what keeps you comfortable underneath your tactical equipment. 5.11 Base Layers deliver durability, comfort, and utility that will help keep you cool and focused when duty heats up and help you unwind when the day is done. Using high-performance materials, garment technologies that warm, cool, and wick moisture, and insight from a variety of users, we’ve crafted base-layer products made for everyday operators. Our innovative holster shirt is a one-of-a-kind CCW undershirt. Our popular crew-neck undershirts are available in loose and accelerated fits, long- and short-sleeves. And our briefs and leggings provide superior support and airflow, giving you one less thing to think about when duty calls. 5.11 Base Layer items are an investment in yourself. A worthy investment.
