Heavy duty Opalo drainage coverall that has it's zipper horizontally on the top of the suit. The model for this item is the 304K drainage coverall.


This 1000g model uses the super thick black or dark olive fabric that they also in their thigh and chest waders!


Have a look at this dedicated info page about the Extreme Drainage Coverall.


Please observe, that the zipper is not watertight, but there will be a storm flap welded above the zipper, so the suit will be ok to wear under heavy rain.


The zipper is normally on the back, going over the shoulder blades, but it can also be placed on the front side.  Have a look at the photos.


The gloves can be either blue (sizes 9 to 11) or dark green 10. 


The size on this one is very generous. You can easily choose one size smaller if you wish and you'll still fit in.


The man with the beard in the dark olive suit is 185 cm tall and 100 kg and is wearing a size XL/56 coverall. The store owner is wearing size XS/48 which is also the same one as he uses on the Extreme coveralls and you can clearly tell that it has extra space in it. But then again, it feels very nice when it's this spacious :)


The chest and waist are 10 cm wider (20 cm more in circumference) than the Extreme Coverall and this also has a couple of cm extra in the height.
