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 have only ever seen one cycle-specific jacket that had a hydrostatic head rating on it. And I grabbed it right away. The Bont, RXL rain jacket. Great cut, long arms and still 'proof 4 years later.

I take it back. 2m = 20,000! So the RAB is actually more waterproof.
