Is Augmented Reality (AR) finally useful for outdoor sports?

We've seen a lot of AR gimmicks, but I've been working on implementing AR for mountain wayfinding (literally pointing your phone at a lift to see where it goes). For those building in the outdoor space: do you think AR is ready for mass adoption in extreme weather (cold/bright sun), or is it still too clunky? Would love to hear your thoughts on the UX challenges.
