I finally came across a use case where my 6 Plus is just too big -- mountain biking. With my old 5, I could slip it into my pants pocket and zip along the trails accompanied by music or podcasts. Potential bending issues aside, the 6 plus is just not comfortable there when biking, and throwing on a jacket keep it in a zippered pocket is just too toasty for a bike ride. I have used mounting brackets in the past but do not trust them fully on non-smooth paths.
With that in mind, does anybody have recommendations for either a wearable case for a 6 plus? I'd prefer one on the wrist instead of the biceps, but most of the established brands seem to focus on the upper arm.
