For a hands-free crossbody phone case without the commitment go for a Smartish Case Clinger. Its nifty tab insert allows you to go strappy one day and off leash the next with any phone, any full-frame case. Its two-way adjustable length you can wear it like a VIP neck lanyard, a shoulder strap, or a shorter wrist leash. And with different styles to match your vibe, go from day hiker, to post-apocalyptic biker, to gala goer with a speedy strap swap.
