After purchasing this stuff online, later discovered they stock it at the local Walmart (camping section) where it was not only it cheaper, the spray can was extra sized.
I like this stuff. Not bulletproof but water and dirt don't stick to packs and equipment nearly as easily.
I've no doubt rain gear is helped by this but: the only heavy rain we saw this year was during strenuous portage and there was no way to know how rainproof it was with all that perspiration.
