If you’re like a lot of hikers these days, your phone is your camera, so it better not be in your pack’s top lid when you need to nail a shot. Enter LifeProof’s LifeActiv armband, which affords instant access to your phone, er, camera. It’s big enough to wear over a few layers, and the detachable mount uses both a magnet and a glove-friendly mechanical lock. Our phones weren’t going anywhere as we ran up and down trails in Nevada’s Red Rocks Canyon.Bonus: Since the mount attaches to any phone, you won’t need a new band every time you upgrade.
