Hydrostatic head - how come one Pertex Shield+ jacket is rated 10,000 and another is rated 2,000? They're similar weights so I assume they're using the same single layer of material. What gives?

I take it back. 2m = 20,000! So the RAB is actually more waterproof.
You get different laminates, one's Pertex Shield+ 2.5 layer, the other's 3 layer.
I see now that 2m = 20,000mm - water column blah blah.
Just not sure which racer to copy - one has RAB one has Castelli. Both have raced last year's TCR. Both are skinnier than me by 20kg+ :)
