Never seen the Forcefield Body Armor -- Looks nice.
In regards to chest protector - I recently purchased the Leatt Chest Protector Adventure Lite. My reason for going with the Leatt is that this one works perfect with my Leatt neck brace!! It is very light and I like it as I can wear it over my jersey.
