The main problem with this suit is that the external shell isn't water proof, and as someone earlier noted is that it does get heavy, it does also give what I would term as moderate to good weather protection and has a good standard of armour, I've green laned in winter in mine and toured also and do love it -
It has weakness is absorbance -this causes excess weight and cold if you don't have enough base layers on in the wet
it has a lot of strengths too i.e. protection and ventilation.
People need to remember that this suit is an allrounder, so there are suits on the market that will offer better inclement weather protection in winter that you will find too hot in summer.... You could say that the R2 bridges the gap of both.
IMHO AFWIW
if you go out in wet and cold only for long distances.. Rukka
in between ridingRallye II or HG..Touareg
Commute - Stich or BMW coverall
Interesting to find out what other peoples three suit choice would be
