My recommendation is to take an old phone, make sure it's charged, and throw it in a Ziploc in a back pocket. Then stay on-trail, which you should almost always be doing anyway.
Sure, use your phone with offline maps as your primary, but a printed backup map doesn't require anything special or expensive.

This is the second response in a row where you've read something I wrote and responded to a very specific thing I did not say.
Last year I went hiking in Switzerland, so I mailed a couple of different maps of where I was going and picked them up from the print shop in town, which took me...... 30 minutes?
The times I've used my phone for hiking I've always regretted it for one reason or another. Maps are so much better, and it's not extensive setup getting your hands on one, one way or another. Come on.
