I had a pair of the Alpina trousers for a number of years. Looked different to the Advance. I liked them for winter use with the liner fitted. The weren't so comfortable in hot weather without the liner, as that was integral to wicking away sweat it seamed. Since then, I have discovered the benefit of EDZ base layers and they would probably work well with a pair of those or some merino ones.
They lasted well and represented good value for money. Can't comment about the jacket. I'd have another pair, if I hadn't moved some distance from my nearest Wulfsport stockist.
Like every other pair of waterproof trousers I have owned, they eventually succumbed to the short, fat bloke on a GS syndrome i.e. they started leaking in the crotch are as the seams there always get stretched as I (dis)mount the bike.
