Features of Men's Massif Nitro Knit Boxer Briefs

• With 37.5 technology, patented active particles permanently embedded at the fiber level capture and release moisture vapor
• By actively responding to body heat, the active particles use this energy from the body to accelerate the vapor movement and speed up the conversion of liquid to vapor, significantly increasing drying rates
• 37.5 technology is made with naturally derived materials so there are no harsh chemicals to irritate skin
• 37.5 active particles are permanently embedded into yarn and will never wash out or degrade
• Flat seam construction minimizes chafing under body armor
• Trim fit allows for concealed wear under uniforms
• Highly compressible for easy packing
