i did wish it didn't fray but they stay so well that's it's worth the tiny bit of fraying. i love all the newer colors and patterns and hope they'll come to the tandem mobi pockets too! those have been my new favorite patch thing when using mobi as patch. i use long tubing often but hated tubing to my arm so now i love your pocket patches on arm with short tube. i do also need to use skintac to make sure it doesn't peel and get funky especially on the first day or if i'm active/warm
