Do expensive diaper bags actually hold up better than cheap ones?

Not consistently. Verified-purchase reviewers flagged durability issues on both budget and mid-priced bags, including a broken main zipper on the RUVALINO and questionable stitching on the Skip Hop Forma. Premium options like the Itzy Ritzy Boss Plus draw stronger build-quality praise, but reviewers warn the leather-look material adds weight even when empty, so price alone isn't a reliable durability signal.
