THOUGHTFULLY DESIGNED BY ATHLETES, FOR ATHLETES

At Sporteer, we don’t just design great products, we use them – EVERY DAY, right here in the USA. We believe athletes deserve products that are actually designed and tested by athletes who understand and appreciate that performance is a result of thoughtful design.

We sweat the details (no, really – we actually do sweat!) and continually adapt our armbands to ensure compatibility with new technology. Our designers are our product testers. We stick to what we know and we do what we love – and that makes all the difference.

NOT JUST FOR RUNNERS!

Runners love the E8 Armband, no doubt, but we didn’t forget non-runners!

The E8 also works great in the gym, on a hike, while dog-walking, shopping, traveling or during any activity requiring hands-free access to your smartphone.

The unique modular design features removable and interchangeable straps to ensure a perfect fit on a bare arm or over clothing. There is no need to have two armbands – simply swap the straps!

MEMORY FOAM BACKING

Soft Memory Foam padding provides comfort and a secure, bounce-free grip on bare arms or over clothing. Slipping down your arm is prevented – even with large, heavy mobile phones and cases.

A moisture barrier behind the foam prevents sweat from entering the zippered pocket, keeping your phone dry.

LOCKING ZIPPER HEADS

The dual-zipper design allows earbud cords to be positioned in any position for compatibility with any earphone jack position or wireless earbuds. The zipper pulls lock in place for security and to prevent annoying rattling while running.

Reflective piping around the touch screen provides added safety at night.

WILL MY MOBILE PHONE FIT? WHICH REMOVABLE STRAP SIZES DO I NEED?

We try to highlight the most popular phones currently on the market and keep up with new devices and cases. However, maintaining a complete list at all times would be impossible and the list is huge!

The best way to determine if your phone (and case) fits is to measure the length and width. Any phone or case up to 165mm X 85 mm will fit, including most iPhones, Galaxy phones, Pixels, and MANY other brands. Please contact Sporteer Customer Support with questions about phone compatibility.

If you have a smaller smartphone, we recommend the Sporteer Velocity V7 Armband. If your smartphone or case is larger than 165mm X 85mm, we recommend a Sporteer Running Belt.

ARM SIZE GUIDE (upper arm circumference): SMALL: 8 – 11 inches (20 – 28 cm), MEDIUM: 10 – 14 inches (25 – 36 cm), LARGE: 13 – 18 inches (33 – 46 cm).

TWO STRAP SIZES INCLUDED:

S/M BUNDLE: Includes one Small Strap and One Medium Strap

M/L BUNDLE: Includes one Medium Strap and One Large Strap.

WE LIVE, WORK, PLAY, AND SWEAT IN ARIZONA, USA

Sporteer is located in Scottsdale, AZ, USA, so you can be assured our products are designed and tested by a team of athletes in the USA – not across an ocean somewhere. Every Sporteer product is created, tested and improved by athletes in Arizona.

When we are not working (too much), you can find us in the gym, on the road or running a dusty trail loop.

Need help selecting the right product? Did you order the wrong product or size? Has your order gone missing in transit? Do you have suggestions? Reach out to us – we’re here and we answer calls (and email).

Bottom line – we have your back and we’re here to help.

CONTOURED MEMORY FOAM SUPPORT: Engineered with a specialized Tapered-Channel foam backing designed to stabilize heavy, large-format smartphones. Thick central pillars provide a solid foundation for your device, while the outer sections gradually taper in depth to allow the armband to curve naturally around your arm for a secure, zero-slip fit
UNIVERSAL DIMENSION COMPATIBILITY: Precision-engineered to fit all smartphone brands and protective cases with maximum dimensions of 165 x 90 x 16 mm. While optimized for flagships like iPhone 17/16/15 Pro Max, Galaxy S26+, and Pixel 10 Pro XL, the E8 is compatible with any mobile device within these specs. Note: For “Ultra” models or heavy-duty rugged cases, we recommend the Sporteer Kinetic K1 Belt
ADVANCED MOISTURE & SWEAT BARRIER: The high-density foam core acts as a physical shield against sweat and moisture. Combined with a premium nylon front and internal moisture liners, your device stays dry and protected during long-distance endurance runs, marathons, or high-intensity gym training
FULL ACCESS TO YOUR PHONE SCREEN: The new, softer touch screen provides full access to your phone screen. Easily control your apps with the touch of a finger or with a quick swipe
ADDITIONAL USEFUL DESIGN FEATURES: Other armband features include locking zippers to prevent rattling, reflective trim on armband and straps for safe running at night, and internal pockets and extra space inside for carrying ID, cards, cash, keys, or other small items
WARRANTY: All Sporteer products have a 1-Year Warranty.
