Should I get a hip pack with a hydration bladder or a water-bottle holder?

It depends on activity. Bladder-equipped lumbar packs (like the Dakine Hot Laps 5L) are favored by mountain bikers who want hands-free sipping, though forum users note bladders are a chore to dry and store. Bottle-holder belts are simpler and cheaper, and trail runners on r/running say a centered, snug bottle pocket that doesn't bounce is the key feature to look for.
