I'm curious if anyone has any hands on experience comparing the DWR of TiGoats 7d versus other lightweight fabric DWRs, like M90 or the .9oz from OWF. I did the usual searches but only found the thread comparing warmth, nothing directly relating to the DWR. Does the 7d DWR stand up over time? M90 seems proven, but I haven't come across much about 7d's performance against spray over time.
I'm trying to decide on the fabric for the top of my MYOG bivy, and the weight savings of 7d would be nice, but not if it doesn't perform, both against wind and spray, as a bivy top.
Like I said, this is for a bivy, so the protection the fabric would offer matters rather than downproof-ness. I haven't ordered anything yet, just constantly rehashing the different options over and over.
Thanks for any help or advice.
