Fireline is an exclusive, new ultra-warm, feather-light and stretchy insulation layer. Consisting of brushed, quick-dry polypropylene lines knitted over jersey, it feels soft and warm to touch. The brushed surface absorbs moisture which is then heated by your body creating a warming, greenhouse effect inside the suit.
Combination of the thin, ultra-stretch jersey base and the line structure of polypropylene make Fireline feather-light and very flexible, aiding maneuverability.
When the suit is drying, the wicking properties of the brushed polypropylene allows the lining to dry rapidly so that you can be back in the water in no time.
