YMMV Review

At the OR Show this last January I had a little time to walk around and check out some of the other booths around the show that were not on my schedule. One booth I stopped at was the SPI booth. I had seen these before but never had the opportunity to try one. Talking to them I really liked how it carried items close to your body and instantly thought of using it for my phone.

Plastic Buckle


SPI sent both Melissa and I a belt to test. They were mainly used for our iPhones. Allowing us to listen to music while running, walking, or working around the house.

“SPI” is short for Small Personal Item, so this is a Small Personal Item Belt. The SPIbelt is made of an elastic belt with a stretchy expandable pouch. The idea was started when the founder was out running and had no good place to put her keys. She then went home to create a better idea and the SPIbelt was born. For a while they were created in her apartment, but have since moved into a more permanent location.

I am not exactly sure of what the main fabric is made of, but it feels like a nylon and spandex mix. It has excellent stretch so I imagine the spandex content is high. The elastic belt is adjustable on both sides with a plastic clip to take the belt on and off. The pocket is 19.1 cm (7.5 in) long and 2.5 cm (1 in) wide when not expanded. The pocket can stretch to 8.9 cm (3.5 in) deep by 11.4 cm (4.5 in) tall. The length of the pocket does not really stretch because of the zipper in the front. The way the pocket stretches is by having overlapping fabric in the back that can stretch to accommodate larger objects. All the seams and construction are solid and simple. There is not much that can go wrong. The belt is low profile and can be worn under a shirt without creating a bulge.

Back of the Pocket

Since I was not able to find out much information on the fabrics. I wasn’t able to determine how they source them. At least, the belts are made in Austin, Texas. For this reason, I gave it a one in sustainability.

Fit ★★★½☆

Adjustability (30%) ★★★½☆

Comfort Next to Skin (25%) ★★★☆☆

Ease of Movement (45%) ★★★½☆

The belt can be adjusted on both sides to optimize fit. It can accommodate waist sizes from 63.5 cm (25 in) to 127 in (50 in). Putting it on is super easy, just adjust to the size you like and clip the buckle closed. To adjust the size all you need to do is slide the adjustment buckles tighter or looser. The elastic belt is soft on the back and does not grab clothing or irritate the skin. The pocket material is even softer to the touch. I never had any issues with the SPIbelt catching or grabbing any of my clothing, even the zipper.

I really like how the belt can stretch; this makes it so it can move with you and not be hindering. I could use it running and walking comfortably. I did try to sling it over my shoulder as a messenger type during one run and it even worked okay for that as well.  By all means it was not ideal, but an option if needed. I mentioned that Melissa got one to test and she had similar results to me.

Performance ★★★½☆

Adjustability of Pockets (35%) ★★★☆☆

Durability (20%) ★★★☆☆

Versatility (35%) ★★★★☆

Weight Distribution (10%) ★★★★☆

Using the SPIbelt has been great. I was getting tired of always needing an armband or using pockets not designed for my iPhone. I like to run with my phone because it has music and GPS on it. Melissa also likes it when I carry my phone on long runs just in case something happens. While the SPIbelt is not made for just carrying an iPhone, it is what I mainly used it for. The pocket can easily carry smaller items and even with the phone in there, there was still room for money and credit cards. One thing I wish the belt had was an audio port out of the side, instead I had to route the headphone cable out through the zipper. It is not a big deal but it does kind of torque my headphone jack.

With iPhone Inside

The belts have been used now about 50 times and have not shown any issues. What is great about the SPIbelt is the versatility. The belt can be used to carry whatever you need to comfortably. It does not get too bulky so you can even use it for traveling and keeping valuables out of view. When wearing the belt with a heavy iPhone, I did not have any issues of the belt bouncing or moving. It stayed in place, which was very impressive. If you plan to use smaller and lighter items I am sure they will stay locked in place as well.

Overall ★★★½☆

Overall, I was impressed by the SPIbelt. It truly is a outstanding alternative to having to use pockets or arm bands. While not all pockets are bad, and I have tested a great armband, it is good to have another option. The SPIbelt has been comfortable and very versatile. There are a wide variety of different colors to choose from so you can match your personality. I have used the SPIbelt, mainly on my runs, but it really can be used for whatever you need to carry small items for. Check it out, you will not be disappointed. It retails for $20, which is a good value. As always, your mileage may vary.

Pros [field name=iFrame]

  • Moves well with you
  • Does not bounce
  • Can accommodate larger objects like my phone
  • Good price
  • Lots of colors available


  • Wish there was a audio port but not a huge deal
