These 3/4 bib knickers use Morvelo's Thermoactive fabric which is a mid-weight, fleece-lined lycra designed to retain your body heat on a cold day without sacrificing too much breathability. The high tech Italian 'Dolomiti' dual layer chamois pad help to minimise pressure points and maximise vatnilatin and moisture control. Comfort is further rnhanced by the use of a new development for Morvelo - Printed Gripper Elastic (PGE) - a far superior alternative to silicone leg grippers, spreadeing the load evenly over a wider, elasticated strip of material to provide the same degree of grip without the need to press so tightly. A great example of the constant search for more comfort and a better fit.
