Get ready to dominate the elements with our ECWCS Gen III Level II Underwear Bottoms. Made from breathable, mid-weight grid fleece material that great for layering, the thermal underwear is designed to keep you warm, comfortable, and dry, even in the harshest weather. The waffle thermals also feature anti-microbial and anti-odor defense, ensuring that you stay fresh and clean through various outdoor or winter activities.

Staying Warm & Dry:

• The base layer pants wick sweat and moisture away for optimum comfort, swiftly transferring it to the top layer for a quick dry. This allows you to move freely without your clothing sticking to you.

Comfortable Fit:

• Constructed of a 93% polyester / 7% spandex blend, the grid fleece material easily flexes and contorts with your body for optimum comfort. These base layer pants feature an access fly, along with an elastic waist and leg bottoms that help insulate your body heat.

Active-Duty Approved:

• The thermal bottoms are part of the Extended Cold Weather Clothing System (ECWCS), and are a must-have for any active-duty personnel or outdoor enthusiast in cold climates. Whether you’re gearing up for a mission or camping up in the mountains, you’ll want to keep a pair on you.

Better Together:

• Stay warm and comfortable this winter with our matching ECWCS Gen III Level II Underwear Top. The base layer shirt features the same breathable, mid-weight grid fleece material as the bottoms, ensuring that you’re ready for the mission at hand.
