Looks like that’s the ET30.  I have no experience with it but it looks like the tear strength is 1.9 lbs/8.5 newtons on the warp and 3.5 lbs/15.6 newtons on the fill.  This is straight out of the product guide PDF that DP emails its wholesale customers.  If someone can find figures for 30d silnylon then you could compare.
Also, it does not have the complete waterproofness of the other Xpac laminates – 5 PSI instead of 200+ like the VX07/VX21/etc. Â I don’t know how PSI converts to hydrostatic head though, if you wanted to compare to silnylon.
