Customise your explorer equipment cases with foam, print and more

Explorer cases are amongst the best options available if you – as an individual, professional, or as part of a business – need to protect high-value, important, or specialist equipment.

Explorer cases are fully waterproof, virtually indestructible equipment cases. Manufactured in Italy using a Polypropylene copolymer, they are available in 30 sizes and four standard colours. Explorer offers performance levels equivalent to Peli and similar hard cases. Explorer hard cases are commonplace in military, engineering, avionics, and numerous industrial applications.

You can further enhance your Explorer cases through several customisation options. Bespoke options include custom foam inserts (produced in the UK by GWP Protective) tailored to your products or kit, external print, bezel kits and more.

As one of the largest official Explorer case UK distributors, you can benefit from competitive pricing, free quotes, and expert advice by working with GWP Protective.

What use Explorer cases?

Tough, durable equipment cases

Manufactured in Italy, Explorer cases are Europe’s answer to the ubiquitous Peli™ cases.

Effectively, they are a high-performance, moulded plastic equipment case that offers exceptionally high levels of protection and a wealth of features.

Explorer cases are guaranteed to protect your tools, equipment, and essential items. The cases resist shock, impact, vibration, being crushed, and general mishandling. Explorer cases are also completely water-tight and come with a manufacturer’s lifetime guarantee.

With over 30 sizes and four different colour options in the range, there is a case to suit virtually any application. The range includes specialist gun/rifle cases and larger models with wheels and additional handles.

Due to their performance, it is common to enhance Explorer cases with bespoke foam inserts. Modifying the cases in this way allows for a precise level of protection, one which can be tailored to the exact requirements of your specific items.

Widely used in military, avionics, engineering and medical applications, Explorer cases are a solid alternative to waterproof cases such as Pelican™ Storm Case™, SKB iSeries, Nanuk, and Hardigg ranges.

Explorer case features

Huge range of features to enhance usability, performance, and protection

Explorer case handle with soft covering


The handles offer two main benefits. Firstly, the ergonomic design makes the case comfortable and easy to handle. Secondly, they have been load tested to ensure their suitability for their intended use and reinforced with corrosion-proof steel pins.

Explorer case purge valve

Pressure release valve

A manual pressure relief valve allows you to equalise pressure between the inside and outside of the case (useful for air travel or if the case is underwater for a prolonged period). The internal stop ring prevents the valve from becoming detached and potentially lost.

A closed Explorer case latch


The latches on the Explorer case range are particularly tough and durable. Manufactured from the same tough polypropylene as the case body, they offer high resistance (keeping contents safe) and a positive lock whilst remaining easy to use.

Explorer case wheels


Larger cases also feature wheels, allowing for heavier items to be pulled along. The wheels feature a bearing for smoother operation and use a durable, long-lasting material. Explorer cases that feature wheels also provide a telescopic handle.

An open Explorer case showing the reinforced hinges

Metal reinforced hinges

The Explorer case hinges are incredibly durable due to corrosion-proof metal reinforcements. These also allow for a “lid stay” feature, whereby the case lid remains open without additional supports. Removable lids are also available.

Open Explorer case showing o ring seal in case lid

O ring seal

When combined with the catches, the O ring seal in the case’s interior means that Explorer cases are completely dust and waterproof (when shut). In fact, the cases are IP67 rated, meaning your contents remain dry and safe even if fully submerged.

Explorer case stacking pattern on outer lid

Stacking locations

The moulded in positive stacking locations/patterns featured on Explorer cases allow for safe and accurate stacking. This feature means multiple cases can be transported and stored together much more safely, preventing them from toppling or falling.

Reinforced padlock loop on Explorer case

Pad lockable

Numerous moulded locations around the case allow the use of Explorer-specific or third-party padlocks. The ability to lock them keeps any valuable contents secured when you are not with the case, helping to prevent theft/loss.

Explorer case performance

Stringent testing to military standards

Being virtually unbreakable and coming with a lifetime guarantee (an indication of how confident GT-Line is in their protective cases), Explorer cases have undergone extensive testing for military applications.

Due to the properties of the Polypropylene copolymer used in the manufacture of the cases, they have high impact strength and low susceptibility to stress cracking/fractures. They are tougher and more durable at lower temperatures too.

The cases also have a surprisingly broad operating temperature range. Whilst not as temperature resistant as aluminium cases, they can withstand temperatures between -33°C to +90°C. This performance makes them ideal for both hot and cold climates.

They also have NATO stock numbers allocated. These codes make sourcing Explorer cases for military or similar applications – where this is a requirement – quick and efficient.

FAQs and additional Info

A selection of the most commonly asked questions regarding custom Explorer cases with foam inserts

In what sizes are Explorer cases available?

There is a wide range of Explore cases, with more than 30 different sizes. The smallest of these is 190 x 125 x 85 mm (dimensions relate to the internal length x width x depth). The largest case in the collection is 1080 x 620 x 400 mm. For a complete list of sizes (and other helpful info), please use this Explorer case size chart.

What colour Explorer cases are there?

There are four standard Explore case colours available. They are black, silver, military green and orange. Bespoke colours are available, but these are subject to minimum order quantities (MOQs).

Where are Explorer cases manufactured?

Explorer cases are manufactured in Italy (Bologna) by GT Line Srl. Having been produced in Italy since 1970, they have developed a broad customer base throughout Europe.

Can I have a custom-sized Explorer case?

Technically it would be possible to have a bespoke Explorer case. However, due to the costs of the tooling, this would result in a very high MOQ (minimum order quantity) or would make the cases very expensive. If you cannot find a suitable size in the Explorer range, GWP will be happy to advise of alternative waterproof cases or manufacture a bespoke EXOcase.

What are Explorer cases made from?

Explorer cases use a Polypropylene copolymer in their manufacture. Polypropylene is a widely used thermoplastic, but a copolymer variant makes the cases slightly softer and more pliable. Whilst this may sound negative, the cases have better impact strength, are more durable, tougher at lower temperatures and are stress crack resistant.

Do Explorer cases have wheels?

The larger Explorer cases have built-in, in-line wheels (and a telescopic handle) to aid movement. However, these wheels and handles would add unnecessary weight to the smaller cases. Please see this size guide to see whether the individual cases have wheels.

Can Explorer cases be customised?

You can customise Explorer cases in several ways. Standard options include bezel kits, padded dividers and straps that allow you to wear the cases like a rucksack. GWP Protective can also design and manufacture protective foam inserts, providing tailored protection for equipment or delicate items (preventing damage).

Can I purchase a single Explorer case?

While purchasing a single Explorer case from GWP is possible, it is likely more cost-effective to do so from an online shop. GWP Protective specialise in supplying mid to high-volume cases to businesses and providing extensive customisation. If in doubt, please do not hesitate to ask – a team member will be happy to advise as appropriate.

What other waterproof cases are there?

The waterproof case market offers a vast array of different brands and products. Options include Peli (Protector) cases, Peli Storm, Nanuk, SKB and Hardigg Roto Mould options, besides Explorer. You can also source waterproof flight cases (EXOcase), which allow the manufacture of custom sizes.

What are Explorer cases typically used for?

The use of Explorer cases by European military forces is widespread, but the cases are also popular in other industries and applications. Typical sectors include field engineers, motorsport, aerospace, broadcasting, and offshore oil and gas. If your business has expensive, delicate or specialist equipment that needs protecting, Explorer cases will protect them.
