I don’t wear a fanny pack because I don’t have much to carry, and when I do, it’s too much to fit in a fanny pack, so I opt for a sling bag, considering I’m not very good at carrying purses/totes.
My dad wears a fanny pack when he goes skiing… we make fun of him… he calls it his “man pack.” mmhmm… very manly, Dad. :laugh:
My mom often carries a sling bag, but recently switched to a fanny pack she got at WDW because you can wear them onto rollercoasters at IOA/Universal (you have to get lockers for your bags there… such a pain).
It depends on personal preference, really. Fanny packs are easy to access, verses the backpack/sling bag you have to take off your back to get into. They can also be worn onto rides, and you don’t worry so much about losing them… or people getting into them without your knowledge. But, you do lose the “coolness factor” a bit.
