Wear it on your belt, sling it over your shoulder, clip it across your chest, throw it in a larger bag. I've already used this bag more than I thought I would. I primarily got it for backpacking for landscape photography but have already used it for other outings.
As far as comfort, my first hike with it was 10 miles with 3000 ft of elevation and I honestly forgot I was wearing it. I used to use a clip system I my shoulder strap and this is tons more comfortable.
Overall great product and at a great price point compared to other chest bags.
