vaporshell jacket waterproof rating

more testing results from independent labs SGS, on the waterproofness ratings on the vaporshell materials:
INTIAL TEST: ASTM D751:2006 Procedure A; Mullen Method, the result from this test was 68000 mm of h20 head of pressure.
NEW TEST: AATCC 127-2008 option 2 Hydrostatic head method, results were 28,000 mm h20 pressure head.
NEW TEST: JIS 1092 - 1998, results were 29,000 mm h20 pressure head.
The waterproofness results in the lab correlate to great waterproofness in the field. in addition the DWR finish and seam taping all contribute to the user staying dry in full on conditions.
The true feature for this jacket however is the breath-ability. the testing has shown great breath-ability, as described as 46000 grams of water being transported through a square meter of material in a 24 hr period. The breath-ability and air permeability allow you stay dry on the inside, by transporting the sweat and vapor given off the body in aerobic activities through the fabric.

I love BC.com, from your customer service, to prices/sales, to the actual stoic brand. It's refreshing to see not just a customer service dressed marketing shill but a director/designer respond to this query. It shows that Backcountry.com does care about accountability. Regardless of if this was a simple mistake or a ploy from marketing, you have given the relevant information as asked for and seems that you will be updating the specs on the website accordingly. Honestly that is the biggest failing of BC.com, your product specs are often incorrect on the website, however the staff does update them as soon as they are made aware of the issue. I commend the effort to address the issues of the community and keep up the good work out there in Utah.
