Hard to beat Aerostich for Easy ON ... Easy Off gear. Great protection, fairly waterproof. Popular with moto commuters wearing Business suits under.
Both MotoPort and Rukka make fine stuff ... but NEITHER are really designed for quick ingress/egress.
MotoPort are expensive, high quality ... Rukka is simply ridiculous money... Way over priced for what it is ... and I've personally seen it torn to bits in a 25 mph crash. Shredded! (rider OK!) Aerostich does better.
BTW, I hope you never leave Northern Europe ... because the gear listed will ROAST you in Summer. If you ever get to tropical zone ... add Par Boil to that.
Aerostich is EXCELLENT if touring in temps from Freezing up to about 85F. Above that it's uncomfortable if stopped or slow going in traffic.
For 20 years Aerostich was one of THE most popular choices for expert touring riders. But things have shifted quite a bit now and Aerostich have not really kept up. Riders have moved on. LOTS more choices now. Look around.
Many touring riders now use more versatile gear that is good in HEAT and Cold. I owned an Aerostich and once on the move it's GREAT ... but it's heavy off the bike, not that warm and mine (9 years back) was not waterproof. But really good crash protection.
MotoPort is tough, vented, works well in hot weather, fantastic protection, but more like wearing military Flack jacket. Stiff, uncomfortable. (for me)
Both Aerostich and MotoPort can custom make a suit for you and send it to you in Belgium. We have this thing called "Postal Service" ... it actually works!
Aerostich, have done on line fittings for decades and know how to get the fit right.
See web site.
The Professionals ... 4 Aerostich suits here ... this is my gang about 5 years back.
