I'm not sure how much it weighs, but my husband only likes to carry his wallet and keys. He'd like to carry his iPhone, but he's a little nervous that even with a hard case and screen protector, something night scrape or crack the screen. He usually hands me his iPhone. I keep meaning to figure out some way for him to feel better about having his iPhone in his sporran since it's not much better off in my purse (I do understand the worry, though). He prefers traveling light, regardless of the iPhone worry though and would probably only have those three things in his sporran at a time.
