I reviewed comments for three different jersey-pocket phone utility bags. I liked the features of this one best. I have used it for four months now, late December to mid-April. So, it has been through 35-85 degree heat, 2500 miles riding, and dry to very humid conditions. My iPhone 12 just fits in the bag. The outer zipper is well made. I have to use a little care when placing my phone inside to keep it away from the tab on the inner zipper. The inside is just big enough to add my tubeless tire Dynaplug Racer Pro repair tool, a small bottle of eyedrops, and a couple of electrolyte packets with the iPhone. The outer vinyl case is water resistant, wears well, and is not so slick to move around when hitting bumps.
I�ve owned the first version of this that is made from recycled inner tubes for a few years wanted to replace it, it was still in good shape but I was curious about the new one. I do like this one better, it has a lower profile and the cushioning is perfect, it holds my iPhone 13 no problem with a few other small items.
Very nice bag. Cushioned, protects the bag well.
