No worries about insert pockets. Can use them underneath any leather or riding jacket

Want a chest protector for the track. This seems to be one of the few CE L2 certified ones.
Supposed to be light, flexible and well vented. My racing suit is tight enough, so this should stay in place.
Let's see if all of this holds true when it gets here. Ship if FAAAAAAST, 'Zilla!

Had a tumble got some cracked ribs also bruising to the chest and back. Anything to make track and race days safer...

Because I don't want to have mushy innards in case of a violent one off.

What Alpinestars jackets are compatible with this chest protector?
Matthew H on Feb 27, 2015
BEST ANSWER: None. This is made for race suits. You want something sold with a harness.
Does this come with some sort of strap or insert to keep it on the chest and body?
Dan A on Apr 3, 2015
BEST ANSWER: Nope, just slide it in when zipping up. If your suit fits right it won't have a lot of room to move. It is also a fairly flexible material.
