I bought the new Triumph Blouson jacket (2007) - much improved over the previous one. I love it, it's water repellent and it will cram into a very small space. The Triumph logo on it looks pretty cool too. It costs $99.
It's lightweight and has zipper vents to let air in, if needed. It can be worn as a lightweight jacket or over a sweatshirt or something for cooler weather. It can also be worn as a regular kick around jacket. It does not have protectors. Check it out.
