These Extreme bibpants are made of the very resistant fabric called Opalo in 700 gram/m2 material weight.
 
The front colour is orange in these ones. It looks very red in the photos.
 
All the seams are double stitched and welded together so you will absolutely not get wet nor the seams tear. The fabric of these pants is shiny on the outside which makes it very easy to keep them clean - just splash the dirt off with water.
 
Two-Colour version (3004) has extra layer of fabric in the knees. The back colour of the bibs and the colour of the kneepads is blue in the two-colour version.
