The protector fits well under my leathers, is light & breathes very well. As my leathers are snug, when trying to remove the suit, it is a challenge to prevent the suit from getting hung up on the shoulder strap attachment points at the top of the protector. To be fair to the protector, I'm new to wearing race leathers & it is a race fit, so I may be doing something wrong. I added the tailbone protector and it also works well.

Great product
I bought this a few weeks back and on you fortnine website it says xsmall and small are same sizing, med and large are same sizing but that is not the case... I ordered the small thinking it would be fine and it’s actually a little long and on the actual card the protector came with it states xsmall is actually smaller (which is what I should have bought) I had a track day the day after it came in so no time to exchange I had to just wear it.
