Sure, thanks, it would be interesting, but be careful as the pants can get ripped for real. On the coat I use for winter I have reflective bands permanently around hand cuffs, with turning being a rationale, and then also have various reflective elements around the bike pointing in different directions.

I presume Arundel might not grab the content well enough. The Profile Design Kage can also accommodate contents that vary at least a bit in diameter. It comes with an O-ring to make it grab the content, which I replaced with an SS spring. Before I used adjustable cages from Topeak, but eventually cracked all of them with grabbed cuffs.
