Glad that Roger clarified the “sil/poly,” at least on RBTR, means silicone coated polyester, not “silicone/polyurethane” coated. Or did he? If one side of the polyester fabric is coated with polyurethane, then it should be “sil/PU/poly;” but bet we’ll never see that on BPL. Obfuscation reigns.
Matthew K – If washing in ATSKO as Roger suggests does not wash out the contaminants from the Tide (liquid or powder), and the jacket still leaks as shown in your excellent photo, then ordering another one could be a problem, as Luke’s Ultralight seems to have gone by the board. Do you take size XL? Somewhere I’ve got an XL of Luke’s WPB rainjacket (gift, never used) made I think of the same WPB material sold on RBTR. Let me know if you want it at scfhome@worldpath.net. Use Roger’s sticky tape suggestion to find out what seam sealer to use.
