Maybe you want to avoid buying a hiking waist pack and just use an old fanny pack instead. I feel your pain when it comes to saving money, but in the long run this could cause more harm on your body. Let’s examine the build quality of a traditional fanny pack. The pack itself is very small with a limited amount of storage capacity and there’s maybe only one zipper to a main compartment. The strap itself is very thin and offers no comfort or padding. A standard fanny pack belt might even be thinner than a belt that holds up your pants.
For the reasons I just mentioned, you should avoid wearing a fanny pack on your next hike. However, if you choose to wear one, I would only bring your cell phone and a pair of car keys. Small items are fine to bring, but the more items you pack, the tighter that thin strap will feel around your waist. If there’s one piece of advice I could give, it’s to avoid packing water bottles in fanny packs at all costs. Standard fanny packs aren’t built to carry water and it will only cause stress on your body. Keep this in mind if you do decide to use a fanny pack.
