I've had/got three Rukka suits over the last 12 years. I've loved them all and will be buying Rukka again. It's my work uniform, after all. Waterproof, comfortable, washes well, protected me in a 40mph spill. They all have that fantastic soft breathable armour.
Can't remember the name of the first suit (and don't have it any more).
I've had an RVP Pro for five/six years - Goretex lining permanently attached to the Cordura outer - a bit too warm in Summer but good in winter.
I've had an AirPower for two years - Goretex lining zips out in warm weather and the Cordura lets air flow through to keep you cool when you're moving or there's a breeze.
Never had any problems with leaks myself until the RVP got crash damaged. The outer Cordura was repaired, but the Goretex lining must have some unseen damage, because when it pours down there is a small leak in the shoulder (where I landed) where water starts to come through after 15 mins or so.
Is it worth the extra? If you're going to wear your suit most days and don't mind keeping it for several years without changing it for the latest 'look', then yes.
