Since Im a Gear Whore, I like topics like these.....
If you have the money, get both but if you can only afford one, you have to look at what your needs are....
If your only riding on weekends and occassional trackdays, the leathers would be great.....
If your riding weekends, commuting, and trips, the Aerostich by far is the best to have......
I personally rather wear an Aerostich period for all the riding I do since I can wear them over my regular clothes if commuting to work/school, or riding on weekends on my favorite roads as El Camino and I-5......
I had a lowside at 70mph and with body armor, it saved me from a world of pain....and I was able to fix any damages to it....
I think there others here that can testify how great the Aerostich suits are......
