The 2XU Tech Speed X Running Singlet for men features 2XU's Ice X with Xylitol
and IR blocking technology to inhibit heat penetration. High level antibacterial
protection and thermoregulation is also assured.
– Body Cooling Tech: Through the use of Xylitol and IR blocking, 2XU has
engineered a fabric for endurance events like no other. Xylitol is embedded in
the yarn of the fabric to draw heat from the body and IR blocking inhibits
penetration of infrared rays to lower skin temperature by up to 5.4°F. The
application of ICE X to polyester/elastane delivers heightened moisture
management whilst high filament yarns and a higher gauge knit are utilized for a
lighter, breathable fabric which also delivers compressive pressure.
