Bliss stuff is usually really good, well thought out stuff, I really like my arg kneepads. But chest/body armour has an incredibly hard job, because most of the time it’s not really the thing that you hit that breaks you- it’s the deceleration, and the momentum of your body. You can definitely protect against that, but the bulk required means nobody’d wear it. So most of the time it won’t really do anything except protect against scrapes. And if you do get the pointy injury that it can protect against, that’s still hard to reduce. Is it worth wearing so much, for those rare occasions?
I kind of like the minimal sides for heat/sweat release but then I figure you’re as likely to land on your side if you wash out as you are on your chest.
