The E Tronic armband is more of a storage sleeve that you can fit your phone into than a sleeve designed for running. We like it for casual runners who don’t need to access their phones during, say, a three(ish) mile run. Slide it onto your arm, stash your cards, cash, wallet, and keys, and then get moving.

Wearing the E Tronic armband is like having an extra pocket on your body. The pros are that you can store your essentials while hiking, biking, rollerblading, or at the beach. However, serious runners may be irritated by the design, as you may feel your items moving inside the sleeve. Or, if you want to quickly check your phone, you’ll have to stop running, take it out, and put it back, which will disrupt your pace.

The band is available in six colors and four sizes. It’s constructed with spandex and nylon to ensure a comfortable fit over various arm shapes and sizes. This may also be one of the most reviewed products on Amazon; it has a four-star rating with over 31,000 reviews.
