Used the performance PRO belt for a marathon and it work so wonderful. Didn't bounce and was solid the whole run!
This belt keeps even large phones stable- no bouncing or chafing. Super comfy to wear- even forget I'm carrying my phone and keys. Great purchase!
Plenty of room for my iPhone, keys, ID card, and iPod!
I love the wider belt on this model and the lined phone pocket. The gel holders are an added bonus. I definitely recommend this to any runner, especially those who already like the other spibelts
I had a couple of original SPI belts in the past and liked them until I started running marathon distance. Then when I was at the Honolulu marathon expo in 2019 I stopped by the booth and spoke to the person there I explained that I needed a wider belt for more secure ride in longer distances but light weight pouch similar to the original. This has exactly that. I am sure that I did not spark the idea but I am very thankful. Love the belt!
