One of the problems I have run into with dualsport riding is being too cold on the street and too hot in the trails. On the newbie dsbc ride I froze my ass off to get there and half way though I was soaked in sweat even after removing a lot of gear.
I think I have found a partial solution now.
I wanted some protection for off road crashes but did not want the full on dirtbike chest protector so I bought a thor impact rig.I can where it under a jacket or jersey and remove the jacket when I get to the trails.
It has pretty good armor and fits very well and is made of mesh type material with good airflow.
It fits under a fleece easily and would probably fit under a ski jacket with no problem.
I got mine at holeshot for $133.
Now I just need to find a good smallish backpack that has a chest or waist strap.
