Interesting. How solid is that face guard? It looks pretty flimsy in
the photo, but these things are very hard to tell from pictures.
It's very hard to tell with plastic structures. The plastic of the chin
guard is about 2.5mm thick, has a medium gloss outer surface and (where
visible) a quite matte inner surface. Much of the interior is covered by
padding. I can't see any evidence of an inhomogeneity (such as one might
get from an internal Kevlar reinforcement, say), and it doesn't have the
smooth curves I would instinctively design for something intended to
resist impact.
But in the hands it's quite strong - it deforms a bit under hand pressure
but it takes a lot of pressure to make it deform. I would certainly
expect it to protect you in the sort of rattling slide down a scree
slope on which I tend to pick up the worst of my mountain biking
injuries but if you fetched up hard against a rock or a tree trunk all
bets are off.
Shades of the coffee thread passim, I /assume/ it is not brittle and if
it failed it wouldn't break into shards which would themselves be
injurious, but I do not /know/ this to be true.
