vaporshell material more testing available

By bill hartlieb May 20, 2011

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 results of the static tests are less than the dynamic test. this makes sense, as the tests are performed differently, and the 'fail' is defined differently. the new static results are still great waterproof testing results, and as good or better than anything on the market - in the $500 range, as well as the $129 range.

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.
