Where are you headed? Three seasons sounds like S. America, since you will ride through pretty much everything: Heat, humidity, rain, cold, snow, wind,
more heat and back again!
I've owned many different types of riding gear, I had a Kilimanjaro about 5 years ago. Good jacket, but things have moved on. The new First Gear jackets are very good IMO. I have a Rainier and it's a very good 3 season jacket. Great in heat, truly breathable fabric, good vents, excellent TPG liner (separate jacket) and very waterproof. In super cold weather you will need a good base layer and perhaps electrics. In hot weather it is really good. I rode in 118F in Death Valley and did great. Also in Baja in 90's. Very versatile for me.
I've heard some good things about the Olympia jackets, tried one on, did not like it. First Gear felt much better and that is what I got. I also have a couple Joe Rocket jackets. Very good. Ballistic 5, the new Ballistic 7 or 8 (?) also gets rave reviews. I also had the JR Alter Ego, not bad.
Check out the First Gear jackets on close out at New Enough:

Also consider the Kathmandu. I've tried it on and its very very nice!!!
