Pockets are never quite enough, especially during a run. Some leggings come without any pockets, and the same goes for classic split-side running shorts. So where do you store your phone? A running belt, naturally.
What exactly is the purpose of running belts?
A running belt is simply a belt you wear while running. Its primary feature is a pocket large enough to fit a smartphone. Depending on the brand and design, it might offer additional functionalities.
Even if your clothes have pockets, you might still prefer a belt. Belts don’t shift around and tend to be more secure, often featuring zippers or other closures, compared to the pockets in your shorts or jacket.
Some running belts offer more than just a space for your phone. Today, I'll compare two belts that are at opposite extremes: the minimalist SPIbelt and the more spacious Flipbelt. Both brands sent me their belts for testing, and I’m here to share my findings.
The minimalist: SPIbelt
The SPIbelt (‘small personal item belt’) is perfect if your primary concern is having a spot for your phone. When I tested the SPIbelt, I forgot I was even wearing it. I zipped my phone in, went for a run, and only realized I had it on after finishing. That’s exactly what you want from a running belt, so I consider the test a success.
The basic SPIbelt is a simple elastic strap that fastens around your waist, featuring a stretchy pocket that contracts to the width of the strap when not in use. (Other versions of the SPIbelt come with two pockets or loops for gels. I tested the classic version.)
The pocket is flexible enough to hold a large phone, or even—as shown on the website—a combination of items like your phone, credit cards, and a house or car key. However, if you plan to take your phone in and out of the belt during your run, be cautious not to lose any of the other items.
The expandable nature of the belt’s pocket can make it a bit tricky. On one rainy run, I wore my SPIbelt over a shirt and jacket. It seemed odd to have the belt over my shirt, so I wore it underneath, but each time I wanted to return my phone to the pocket, I had to lift up the jacket, then the shirt, find the zipper, and use my fingers to expand the pocket before I could slide the phone back in.
In general, it’s a great option if you don’t need frequent access to your phone, or if you don’t mind a little effort when you do.
The maximalist: Flipbelt
Carrying lots of items? You'll want to consider a belt at the other end of the spectrum, one that offers more storage space.
The classic Flipbelt is essentially a wide fabric tube with openings that allow you to stuff items inside. A phone slips right in, no issue. If you're carrying gels, a trail map, a wallet, a tube of Bodyglide, or even a bag of trail mix, there's plenty of space for all of it. I was initially concerned about losing my car key—what if it slipped out?—until I discovered that the belt includes a small tether with a clip. Simply attach your key ring and tuck it inside.
The classic Flipbelt has four openings, all located along the centerline of the belt: two in the front and two in the back. The name 'Flipbelt' comes from the fact that you can turn it inside out, placing the openings against your body for added security, ensuring that nothing will fall out. (There’s also a version with a zippered pocket for extra protection.)
That said... nothing will fall out. The belt's stretchiness holds everything securely in place, and its snug fit prevents it from bouncing. Like the SPIbelt, it can be a little uncomfortable when worn empty; I found that it tended to scrunch up. However, when filled with a phone or other items, it stays put perfectly.
There are two drawbacks to the Flipbelt. One is that it’s not adjustable; you must choose your size, just as you would when buying a pair of pants. (The XS fits kids with an 18" waist, and the XL fits up to 48".) The other minor inconvenience is that being made of fabric, it tends to get sweaty. After each run, I found myself washing it alongside my other clothes. The classic Flipbelt uses moisture-wicking fabric, though there’s also a Flipbelt Air made from mesh.
But, oh, how wonderful it is to have all that space during a long run. I was pleasantly surprised to find that I could fit a standard 16.9-ounce disposable water bottle into the belt, carrying it bounce-free across the small of my back. (Flipbelt also sells curved 6-ounce and 11-ounce bottles that fit more easily.) And if you need even more room, they offer high-waisted leggings with Flipbelt-style pockets (two openings in the front and a zipper pocket in the back), plus generously-sized side pockets on both legs.
How to choose the ideal running belt for your needs
If your goal is to carry just your phone with minimal hassle, go for the SPIbelt. Other brands offering a similar style include Nike and Back Bay.
If you want to carry your phone along with a couple of smaller items (like a key), opt for the 2-pocket SPIbelt.
If you're training for a marathon and need space for snacks and various gear, the Flipbelt is your best bet. (Or better yet, consider the leggings.) Similar styles can be found from brands like Lululemon and Naked.
If you need to carry water, get a Flipbelt with either the custom bottles (they offer single bottles or a three-bottle set), or like me, use a bottle from the grocery store.
If you prefer water that's more accessible, consider a hydration belt with small bottles, like this one from Nathan. You could even fill one with water and the other with electrolytes or a sports drink. Alternatively, try this clip-on bottle from SPIbelt, which can attach to any of their belts, another belt, or simply the waistband of your shorts. By the way, you are wearing some kind of clothing, right?
