The Peak Design City Sling holds only what actually matters on the days a full bag doesn't make sense. It carries crossbody or around the waist, so it's ready to move however the day calls for it, keys, wallet, phone, and nothing else weighing us down. A recycled nylon shell with a water-resistant finish means a quick errand in questionable weather isn't a reason to leave it at home. What Our Gearhead(R) Experts Are Saying:"I wear mine around my waist on days I'm running around the neighborhood and don't want a strap sliding off my shoulder every five minutes. It stays put and I forget it's even there."
