I got my first "man-purse" when I was in high school in the 70s. It was a Sacs Millet day pack purchased from REI. I hammered on the day pack for well over a decade. It took me through high school, college and got me into the grad school, hauling books and going on day hikes. The problem with backpacks when moving around town is that you have to take them off to get stuff out of them.
In grad school, I switched to courier bags. My first was a monster "Doc Martin" bag. This was before Timbuktu even existed. I still have courier bags and they work well as a laptop bag. Courier bags are great in that they allow you to spin the bag around your back. The problem with courier bags is that they require you to lift a flap to get stuff out of them.
A few years ago, I got a sling pack. I hoped to combine the zipper access of a day pack with the spin around the body aspect of a courier bag. This worked OK around town. The problem with a sling pack is that they become uncomfortable on long day hikes.
I'm several month into using a Mountainsmith Day Lumbar pack. It's sold as a lumbar pack but it has a shoulder strap, allowing it to be carried over the shoulder like a "purse" (there, I said it) or across the chest like a courier bag or sling pack.
This pack rocks
This is not my picture...
The really cool thing that really surprised me is the way the shoulder strap and waist belt work together. Putting on a lumbar pack is a pain in the neck. With the shoulder strap, I just put it on across my chest, let it hang from the shoulder strap while I put on the waist belt. If I need something, I can release the waist belt, and bring the pack to the front. In the woods, it carries better than any sling pack and even better than a day pack of the same volume. In town, it works like a shoulder bag and better than a courier bag due to the zipper access.
Only downside is the volume. It's enough for essentials and and windbreaker. It's enough for around town and short day hikes. Longer hikes and I reach for a full sized day pack.
Confident in my manhood....
