Buying a protective case: how to compare materials, fit and level of protection

A protective case should shield your device or equipment from scratches, dust, moisture and knocks during everyday use. However, protective cases can vary considerably in material, fit and the level of protection they actually offer. If you focus only on claims such as “rugged”, “outdoor” or “waterproof”, you could end up with a case that quickly becomes impractical or does not fit your product.

Three things are particularly likely to lead to the wrong purchase:

  • Unclear compatibility: A universal case may have too much room inside. Your device can move around in transit, leaving it less protected.
  • Overstated water-protection claims: Water-resistant material does not automatically mean a case is waterproof or suitable for heavy rain.
  • Unsuitable dimensions: A case that is too tight puts strain on fastenings and seams. If it is too large, your device may not stay securely in place.

Before you buy, consider where you will use the case, your product’s dimensions and the level of protection you need.

Key features to look for in a protective case

1. Fit and internal fastening

A case designed to fit your device helps prevent it from moving around in transit. For a carrying case for a portable espresso machine, elastic straps, interior padding or rigid inserts can be useful. For an e-reader, precise cut-outs for the buttons and ports are also important, as is a magnetic closure if the model has one.

Before you buy, check:

  • Is your exact device model listed?
  • Do the internal dimensions match its length, width and height?
  • Can you still access important ports and controls?
  • Is the product held in place by elastic straps, tabs, padding or a fastening?

For example, a Bigme B6 case should be specifically designed for that model. A generic tablet case may have similar external dimensions, but the cut-outs or closure may not line up.

2. Material and level of protection

An EVA protective case has a moulded, rigid EVA shell that provides a sturdier outer structure than a simple fabric bag. EVA can help protect against everyday knocks and pressure from the outside. Polyester or polyurethane-coated fabrics can also help protect the surface from dirt and light moisture.

Pay close attention to the manufacturer’s exact wording:

  • Water-repellent or water-resistant: Suitable for splashes or light moisture, depending on the construction and zip.
  • Waterproof protective case: Only assume it is waterproof if the manufacturer’s information and the design of the closure clearly confirm this.
  • Impact protection: A rigid shell can help support the structure, but it is no substitute for careful handling after a serious drop.
  • UV protection: For a parasol cover, resistance to outdoor conditions matters more than a soft appearance.

A case with a covered zip is not automatically suitable for submersion. Moisture can still get through seams, openings or fastenings, even on coated surfaces.

3. Dimensions, closure and ease of use

Do not confuse the external dimensions with the usable internal dimensions. The stated external dimensions of the OutIn model are 265 × 110 × 125 mm. The case is designed for selected portable OutIn espresso machines, so check that it matches your exact model before buying.

The closure also affects how practical a case is for everyday use:

  • Zips should open and close smoothly without rubbing against your device.
  • A carry handle is useful for commuting, travelling and camping.
  • External attachment loops can hold a carabiner or small accessories.
  • A parasol cover should be easy to pull on and close securely, despite its larger shape.

Care and lifespan of a protective case

How long a case lasts depends largely on how you use, store and clean it. Check it regularly for split seams, damaged zips and deformations. For the products mentioned, dirt can usually be removed with a soft, damp cloth. Harsh cleaning products and abrasive sponges can damage coatings or surfaces.

For a parasol cover, make sure the parasol is fully closed and secured, and only cover it when dry. Before placing a device in an EVA carrying case, make sure it is dry and securely fastened inside. Moisture trapped in a closed case can lead to odours or material damage.

Frequently asked questions about protective cases

Is a water-resistant protective case waterproof?

No. Water-resistant materials can protect against light splashes or brief exposure to moisture. A case like this is not automatically suitable for heavy rain, prolonged wet conditions or full submersion. Always check the manufacturer’s specific information about the material, zip and seams.

How do I find the right size for a device case?

Compare your device’s dimensions with the case’s stated internal dimensions or compatibility information. For model-specific products, make sure the exact product name matches. A little extra room can be useful, but too much will make it harder to keep your device securely in place.

How can I extend the life of a protective case?

Wipe the surface with a soft, damp cloth, let it dry completely and avoid storing it in direct sunlight for long periods. Operate fastenings without forcing them. For carrying cases, using the internal fastening system correctly helps prevent your device from knocking against the sides unnecessarily.
