When traveling with electronics, you need a hard-shell protective case with an IP67 waterproof rating, impact-resistant construction, and a customizable foam interior that holds your gear securely in place. These features protect against the two most common travel threats: physical impact and moisture. The sections below break down exactly what to look for and how to match the right case to your specific gear.

What features should a travel case for electronics have?

A travel case for electronics should have an impact-resistant outer shell, a watertight seal rated to at least IP67, a pressure equalization valve, and a customizable interior that prevents your gear from shifting during transit. These four features address the core risks electronics face when traveling: drops, water exposure, air pressure changes, and internal movement.

Here is what each feature does in practice:

  • Impact-resistant shell: A polypropylene or high-impact resin outer shell absorbs and distributes force from drops, knocks, and rough baggage handling. The material matters more than thickness alone.
  • IP67 waterproof seal: A rubber gasket running the full perimeter of the lid creates a watertight closure that keeps rain, splashes, and brief submersion from reaching your gear.
  • Pressure equalization valve: When you travel by air or move between altitudes, air pressure changes can make cases difficult to open or cause seals to strain. A valve equalizes internal and external pressure automatically.
  • Custom foam interior: Pre-cut or modular foam holds each piece of equipment in a fixed position, preventing items from colliding and absorbing vibration throughout the journey.

Secondary features worth considering include secure latch mechanisms, padlock-compatible hasps, ergonomic handles, and wheels for larger cases. These add convenience without compromising the core protection.

What’s the difference between a hard case and a soft case for electronics?

The key difference is structural protection. A hard case uses a rigid outer shell to absorb and deflect impact, while a soft case relies on padding alone to cushion gear. Hard cases also provide waterproof and dustproof sealing that soft cases cannot match. For valuable or fragile electronics, a hard case offers a fundamentally higher level of protection.

Soft cases are lighter and more flexible, which makes them convenient for everyday carry when gear is not exposed to serious risk. They work well for accessories, cables, or equipment that can tolerate minor bumps. However, they offer no meaningful protection against crushing force, water ingress, or dust contamination.

Hard cases are the right choice when:

  • Equipment is expensive or difficult to replace
  • Travel involves checked baggage, cargo transport, or outdoor environments
  • Gear includes fragile components such as lenses, sensors, or screens
  • Conditions involve rain, dust, sand, or extreme temperatures

The trade-off with hard cases is weight and bulk. A well-designed hard case with wheels and a telescoping handle largely offsets this for larger loads, but for minimal carry situations, a soft case may still be the practical choice for lower-risk gear.

What does IP67 mean for a protective electronics case?

IP67 is an international protection rating that certifies a case is completely dustproof and can withstand submersion in water up to one meter deep for up to 30 minutes without water entering the interior. The “6” refers to total dust protection, and the “7” refers to the submersion resistance level. For travel with electronics, IP67 is the benchmark rating to look for.

The IP rating system is defined by the IEC 60529 standard and covers two types of protection. The first digit rates solid particle protection on a scale from 0 to 6, where 6 means no dust can enter under any conditions. The second digit rates liquid protection on a scale from 0 to 9, where 7 means temporary submersion is handled without damage.

In practical travel terms, IP67 protection means your case can handle:

  • Heavy rain and wet conditions without sealing failure
  • Dusty environments such as construction sites, deserts, or sandy beaches
  • Accidental drops into shallow water
  • High-humidity storage without moisture entering the case

This rating is achieved through a continuous rubber gasket that runs around the lid perimeter. The quality of that gasket and how consistently it seats against the case body determines whether the IP67 rating holds over time with repeated use.

How do you choose the right case size for your electronics?

Choose a case size by measuring your largest piece of equipment and selecting a case with interior dimensions that accommodate it with enough room for foam padding on all sides. A general rule is to allow at least 25 to 30 mm of foam clearance around each item. Going too large wastes space and allows gear to shift; going too small means inadequate padding.

Start by listing every item that needs to travel in the same case. Measure each item at its widest, longest, and tallest points, including any attached accessories such as handles or lens hoods. Then consider whether items will be stored side by side or stacked, and whether any items need to remain attached to each other.

Practical sizing steps:

  1. Measure your largest item in all three dimensions
  2. Add at least 50 to 60 mm to each dimension to account for foam on both sides
  3. Check that the combined footprint of all items fits within the case’s interior floor area
  4. Verify the case height accommodates your tallest item with foam above and below

If you are unsure between two sizes, choose the larger one. A custom foam interior can always be configured to fill extra space and hold gear firmly, but a case that is too small cannot be adjusted. With over 40 case formats available, finding a size that matches your specific gear configuration is straightforward.

Which electronics benefit most from a hard protective case?

Electronics that benefit most from a hard protective case are those that are expensive, fragile, difficult to replace, or regularly exposed to harsh conditions during transport. This includes cameras and lenses, drones, audio recording equipment, laptops used in field environments, medical devices, and measurement instruments. The higher the replacement cost and the more demanding the travel conditions, the stronger the case for hard-shell protection.

Camera systems are among the most common use cases. A camera body with lenses represents a significant investment, and a single hard impact or water exposure event can cause irreparable damage. The same logic applies to drone equipment, where gimbals, sensors, and propeller assemblies are all vulnerable to shock.

Other electronics that regularly travel in hard cases include:

  • Audio equipment: Microphones, recorders, and mixing hardware used by field production crews
  • Test and measurement tools: Multimeters, oscilloscopes, and calibration equipment used by technical teams
  • Medical devices: Portable diagnostic equipment transported between clinics or used in field settings
  • Broadcast and AV gear: Cables, converters, and signal equipment used on location
  • Outdoor electronics: GPS units, communication devices, and navigation tools used in remote environments

Consumer electronics such as tablets and smartphones used in everyday commuting generally do not require hard cases. The threshold is whether a single damage event would represent a serious financial or operational loss.

Are hard cases allowed as carry-on luggage on flights?

Yes, hard cases are generally allowed as carry-on luggage on flights, provided they meet the airline’s size and weight limits for cabin baggage. Most airlines allow carry-on bags up to approximately 55 x 40 x 20 cm and 7 to 10 kg, though these limits vary by carrier. Always check the specific airline’s policy before traveling, as limits differ between economy and business class and between carriers.

Hard cases that exceed carry-on dimensions must be checked as hold luggage. For checked hard cases, the pressure equalization valve becomes especially important. The cargo hold experiences pressure changes during flight, and without a valve, a sealed case can become difficult to open or place stress on the gasket seal over time.

A few practical points for flying with hard cases:

  • Measure your case against the airline’s published carry-on dimensions before you travel
  • Use padlock-compatible hasps and TSA-approved locks if checking the case as hold luggage
  • Confirm the pressure equalization valve is unobstructed before boarding
  • For lithium batteries, check airline regulations separately, as battery transport rules apply regardless of the case type

Many professionals who travel with camera equipment or audio gear specifically choose compact hard cases sized to fit within carry-on limits. This keeps valuable equipment in the cabin rather than in the hold, where it is subject to heavier handling.
