Product Summary

The SPIbelt is a running belt designed with stretchy material to have a low profile and expand to hold your belongings on your run. SPI states that the SPIbelt is compatible with all phones and has an extensive list of phones that can fit into the belt on their website. Along with your phone, the SPIbelt can hold your keys, credit card, ID, and energy gels. However, many reviewers found it difficult to fit more than a phone.

SPI claims the belt is bounce free and will not ride up or move around while you run. The belt fits waist sizes from 25 to 47 inches. SPI also sells a belt expander which increases the waistband size by 12 inches. The sturdy buckle and glides are designed to hold up during even the longest runs and the soft elastic is designed to prevent chafing.

The SPIbelt is popular among runners for being lightweight and holding essentials securely without bounce. Customers have also used this belt for cycling, walking, and visiting theme parks. Many buyers even returned to purchase a second belt as a gift.

People that disliked the belt complained of difficulty getting their phone in the pocket or being unable to fit anything along with their phone. People have also complained about not being able to get a single item out of their belt: When they unzipped their belt every item inside would fall out.
