I bought a RevIt Dragon jacket about three months ago. It replaced my old, unarmored leather jacket. I like the RevIt Dragon. IMHO, it is well-designed and a good value.
I also have Olympia Airglide 2 pants. It is hard to compare apples and oranges, but I would say that the RevIt is a better quality product overall. There are positives and negatives about each brand.
You can probably save money by buying gear over the Internet, but in this case, you need to try on the jackets before purchase. Like most jackets with removable liners, it should be snug when all the liners are in, but not constricting. Otherwise, the jacket will be too loose when you take the liners out. The velcro straps on the arms and waist help with easy adjustments (off the bike). I tried many jackets at the local BMW dealer before buying the Dragon from them. How they fit was a key factor in my decision. While trying them on, I sat on one of the bikes in the showroom to see how they feel while riding. My second choice would have been the Cayenne.
I haven't had the courage to trust the pants or jacket inner liners in the rain. I use Froggs Toggs over the outside of my gear and they work well. They are easy to put on and take off when needed. Installing and removing liners can be annoying, especially if you are compulsive about those little snaps and loops at the ends of your pant legs and sleeves. The RevIt jacket has two liners - rain and insulation. To add the rain liner, you have to remove the insulation liner if it is installed, put the rain liner in, then put the insulation liner back in. If you don't care about the little snaps at the end of your sleeves, you can add a liner quickly - zip/zip/done. Most of the time I know which liners I want (or not) before I go riding.
Removing (hot day) and installing (cold night) the liner from the Olympia pants cost me too much time on an Iron Butt B2B Extreme ride (24 hours). You have to take the pants off to change them, which is probably true for all pants with removable liners. I had to settle for the standard B2B in under 36 hours.
Here is a good review of the RevIt Dragon. I have the black with high-viz yellow highlights as shown.
