I agree, my Halvarrsons were good , but now are not. 6 years wear on a mostly daily basis, weekend ride outs and about 60k in them. Happy with them, but they are now leaking esp in the crotch area which is not ideal when arriving at work...Also from behind the knees strangely enough. Maybe its the angle or continual bending that creates a weak point through use etc. I'd have them again but if I'd prefer to stretch to a pro shell and avoid sodden textiles dripping all over....If the streetguard is any good then a 2 year warranty with them for £180 quid is a good deal. If they don't leak and don't need to go back and forwards too often etc. If they leak after that, it's been £90 a year. Halvarssons shell are £400 with the same warranty i.e £200 a year..Rukka (goretex) are around £600 for 6 years...but it's not an easy 600 I have lying around. I'd agree Rukka isn't all that much better cost wise, but with their own 6 year warranty and Gore's "guarantee to keep you dry" warranty it's a tough choice.
A choice made easier though if you consider that one Rukka suit pays for two Halvarssons suits!?
That was my way of looking at it. If I get 5 good years from my Halvarssons gear, I can afford to buy another suit for the price of one Rukka suit.
