Well you need to tell us more about your style preferences; from your profile it says you are 24. Since you own an SV I will assume you are extremely cool and not pretentious. I live in VA and commute to work year round (if road conditions permit) and like to tour on my SV. So I am pretty much exposed to every thing from 17 degrees to 100 + humidity. I have found a combination of pants that work for me in all those situations.
Before I get too far, let me describe myself so my recommendation makes some sense. I am 46 and ride more aggressively then I should on the street. 18 yrs ago I did a spectacular flying high side and was messed up pretty bad, so I spare no expense when it comes to safety. I also am married to great woman so I am not really concerned about how I look on the bike; so after safety comfort is my biggest concern
The basis of my pants setup is CyclePorts Ultra II Kevlar pants with stretch Kevlar. I know they look like parachute pants from the 80?s but once your begin to gain weight and loose hair you don?t really care if you wear parachute looking pants!!!! These pant come with a removable Gore-Tex liner. In the summer months I wear shorts under the pants and they breath much better then jeans and what even better is for some reason the black Kevlar does not retain much heat? The only real issue is the large amount of armor which tends to block some breeze. I actually believe that they are cooler then wearing just shorts because as mentioned above, they reduce the heat from radiation directly on the legs. When it gets a little colder or wetter I add the Gore-Tex liners but the Kevlar does not absorb water so they don?t get heavy.
When it starts gets really cold I add my Campmor windproof fleece pant with full leg zips under the Gore-Tex. And when it is in the 20?s or below I add a 4th layer which is Patagonia stretchy expedition weight fleece. The key besides protection and warmth is that most of this stuff has a little stretch to it. Note, I also own a full set of Widder electrics but I did not use them last winter riding in 17 degree weather because I didn?t need them, dirtbike style bar end covers and heated grips did the trick.
The down side is that since they are custom made they cost a lot and take around six weeks for the time you order to you take delivery. However, out of all the stuff I have used in the past, this stuff works the best for me.
Good luck, be safe, and ride like hell....
