As it has been a year, I figure that it's a good time to reflect on my experiences with my thigh pouch, and in general, those experiences have been positive. I wanted (and even designed) a thigh pouch decades ago to deal with my wallet (and later my phone) problem. Basically, keeping my wallet in my back pocket while sitting was torqueing my spine and hip and keeping it in my front pocket was uncomfortable and impractical. This meant leaving my wallet or my phone (or both) in my coat pocket, or in my bag, or in a compartment of my car--and sometimes forgetting and leaving it (them) there.
The thigh pouch allows me to keep my wallet and phone (and sometimes other items, like a pen) on my at all times. It also provides easy access to them even when seated in a car at a drive-thru. It does not get in my way as chest or belly bags can tend to do. Most of the time (except when I was having difficulty with my left arm), I keep it on my left side which has worked well for me from an ergonomic standpoint, especially since the pouch hangs at the perfect reach distance for my arm.
There are a couple of downsides. One is that it is a bit too bizarre for me to take to church, especially as I stand in front of the congregation for the singing of the Psalm. For that matter, it draws a good deal of attention, and sometimes in ways that make me feel that people are uncomfortable around me--perhaps thinking that I have a holstered weapon in it (which is one reason why I have moved away from my earlier name of "wallet holster"). Another is is that at first, there had been a squeak from some of the metal clasps, but thankfully, WD-40 solved that issue. I also do not cinch it too tightly, so the pouch tends to more around my leg a bit if I'm walking too fast (let alone jogging or running). It also tends to loosen over time requiring me to readjust it with noticeable regularity.
However, all told, the positives have certainly outweighed the negatives. It's made a real difference in both my access to my wallet and phone, and my piece of mind in knowing that I have them with me. Even when travelling, it was tremendously helpful to have my wallet, phone, Air Pods, and charging block and cord all contained in the one pouch that I could easily remove and put in a bin to be scanned, and then just latch them back on. Basically, it's precisely what I wanted.
