The performance of traditional turnout gear usually requires a tradeoff between thermal protection and breathability. Increasing one typically means giving up some aspect of the other. Now with the GORE® PARALLON™ liner system, it’s possible to achieve unparalleled levels of breathability, while also preventing serious drops in thermal protection that can occur as your gear gets wet, particularly from sweat. This unique multi-barrier liner system that physically replaces the moisture barrier and thermal liner in conventional gear provides more consistent thermal protection while maximizing the transfer of excess heat away from your body.
