Not necessarily, but carry-on travelers benefit from a toiletry bag that stays compact and meets liquid restrictions. Smaller, well-organized bags make security checks faster and help prevent overpacking liquids.

Hanging toiletry bags work well in hotels and shared bathrooms because everything stays visible and off the counter. Flat toiletry bags are usually more compact and better suited for minimalist or carry-on–only packing.

The best size depends on how you pack, but most travelers do best with a medium-sized bag that holds daily essentials without encouraging extra liquids. Oversized bags often lead to overpacking and security issues.

Most travel toiletry bags are water-resistant rather than fully waterproof. Leak protection depends more on how liquids are packed, so using sealed bottles and zip pouches inside the bag is recommended.

With regular travel, a quality toiletry bag can last several years. Frequent travelers may replace theirs sooner due to wear, zippers, or changing packing needs rather than complete failure.

The travel accessories that save the most space are packing cubes, compression bags, compact toiletry bags, and foldable travel items designed specifically for carry-on efficiency.

The most effective space-saving travel accessories include:

• Compression packing cubes – Reduce bulk by compressing clothing while keeping items organized

• Slim or hanging toiletry bags – Maximize vertical space and prevent overstuffed compartments

• Collapsible travel bottles – Hold liquids without rigid plastic taking up unnecessary room

• Foldable shoes or shoe bags – Protect clothing while minimizing wasted space

• Packable laundry bags – Separate clean and dirty clothes without extra structure

For international travelers packing carry-on only, these accessories help eliminate wasted space, improve organization, and make it easier to access items without unpacking everything.
