Bests & Worsts Reviews from Amazon

I purchased this primarily to hold my passport securely for a trip I am taking later in the year. I have tried it out on long walks to see how comfortable it was and how secure it seemed. Pros: 1. It is not too tight. I wasn't sure from the photos if this would be a problem, because I intend on wearing it for several hours at a time and anything too tight would be out of the question. For reference, I am 5'2" and about 105 lbs. and depending on manufacturer my clothing size can vary 0-2-4. I bought the xtra small taking the advice of other reviewers who said to size down if unsure -- good move. 2. The fabric is really soft against the skin, a satin like feel. 3. It has several deep pockets with a small flap that folds over the top. One pocket easily fit my passport & iphone (5S) with room to spare. I thought the phone might be heavy and uncomfortable but I could almost forget I was wearing it. I only used it for long strenuous walks (did not jog) but everything stayed put and there was no riding up of the contents or fear that I would lose anything. Cons: right now the only thing I can think of is that it may not be ideal in very hot climates worn for long periods of time if you tend to feel warm easily. But right now I feel this is a really great option for my purposes and I may be getting another for a friend.
