im wondering if you have to seam seal this with mcnetts seam grip like all the other silnylon offerings from BD?
It's a decent idea. You don't really have seams that are exposed to the direct force of rain like you would on a tent, but it can still seep in.
I bought the BD Spotlight bivy, nearly the same as this one, and I did have to seam seal it myself
