These bib pants are by far the best heavy matte rubbery feeling bib pants there are.
These are also very thick at 700 grams/m² using Plavitex Heavy Duty -fabric.
Double welded high frequency seams will also not tear. These will keep you 100% protected against rain, wind and salt water.
If you'd like these together with a matching smock, get the set-version of these and save 20 euros.
I would like to note out that these are for the slim people. The person in the photo is 171 cm tall and weighs nearly 80 kilos and there is not much extra space in the size S/50 bibs he's wearing in the photo. If you need something that is wider (or shiny), go for the Viking Standard line.
