I love the SPI Solo-Pocket. It fits my car key, credit card, and lipstick which is all I need when I go shopping. I even wear it around my waist (of course) with my tee-shirt over it. No one even knows I have it on.
These extra add-on pockets are great! I've added one to my dog's leash to hold a roll of poop bags, my house key and whatever else. Once I figured out the best placement, I sewed a couple stitches to keep it in place semi-permanently.
Great addition to my original SPI belt. It is nice to carry phone and fuel in a secure manner during long runs and rides.
Can't go wrong getting a SPI Solo Pocket. I use them for walking my dog or hiking. Can carry my keys, phone and credit card.
Got here fast. It's convenient to have an extra pouch when needed. Works just as advertised.
