How come none of these The North Face packs have the Rain Cover? Spire, Terra, Prophet? How water proof/resistant is the material?
Most packs don't come with a rain cover. You usually have to purchase one separately. The fabric will resist a light amount or drizzle or short periods of rain (1-2 minutes), but if you are expecting rain, definitely pick up a rain cover.
