Waterproof
Waterproofness is the height of a water column, in mm, that the fabric holds before water gets through. 50,000 mm is a column of water 50 metres high, roughly a 16-storey building, pressing on the fabric.
Lab-tested beyond 61,200 mm: all five fabric samples exceeded the test maximum (JIS L 1092 7.1, Method B). Our requirement for Barrier CT Pro™ is 50,000 mm.
