Peli Storm Cases: The Complete Used Buyer’s Guide

The Peli Storm range represents Peli’s evolution of the classic protective case design, and buying a used Peli Storm case in the UK is an excellent way to get premium waterproof protection at a sensible price. Storm cases differ from standard Peli cases in several important ways, and understanding those differences will help you decide whether a Storm case is the right choice for your application — and which model to look for.

What Is a Peli Storm Case?

The Peli Storm series — also referred to as iM cases in some markets — was introduced as a lighter-weight alternative to the original Peli case range. Storm cases use a co-moulded construction with a double-layer wall that combines rigidity with reduced weight. The most visually distinctive feature is the HPX high-performance resin construction and the integrated soft-grip handle with a stainless steel insert.

Storm cases use a different latch system to standard Peli cases — a Press and Pull latch that opens with one hand — and feature the same automatic pressure equalisation valve and O-ring seal found across the Peli range. All Storm cases are rated to IP67: waterproof to one metre depth for 30 minutes, and fully dustproof.

How Do Storm Cases Differ from Standard Peli Cases?

The main practical differences are weight, handle design, and latch mechanism. Storm cases are typically 10–15% lighter than their standard Peli equivalents at the same internal volume, which matters when weight is a consideration for travel or deployment. This weight saving comes from the co-moulded double-wall construction, which uses less material than the solid-wall construction of the classic Peli range.

The Press and Pull latches are faster to operate than the double-throw latches on classic Peli cases — a meaningful advantage when the case needs to be opened and closed frequently in the field. The trade-off is that some users find the standard Peli latch system more positive and secure under heavy loads or rough handling. Both ranges deliver identical IP67 waterproofing and MIL-SPEC crush resistance.

Popular Peli Storm Models: Dimensions and Best Use

The iM2200 is a compact carry-on size case popular with photographers and medical responders. The iM2750 and iM2975 are larger cases well suited to broadcast camera systems and sensitive equipment sets. At the top of the carry range, the iM3220 and larger models handle long items like rifles, tripods, and surveying rods. All of these models appear regularly in the surplus market.

What to Check When Buying a Used Peli Storm Case

The Press and Pull latches should open and close smoothly without sticking or requiring excessive force. If they feel sticky, a small amount of silicone lubricant usually resolves this. The O-ring seal should be intact and seated correctly — Storm cases use the same replaceable seal as standard Peli cases, so replacement is inexpensive if needed.

The handle should be secure with no cracking at the hinge points — this is a common stress point on heavily used Storm cases and worth examining closely. Interior foam condition varies; pick-and-pluck foam in good condition is ideal, but replacement sets are available for all models. The shell should be free of cracks, particularly around the latch mounting points and corners, which can be stress points on cases that have been dropped or heavily loaded.

The automatic pressure equalisation valve — a small button-like feature on the case side — should move freely when pressed. This valve allows air pressure to equalise when flying or moving between altitudes without compromising the waterproof seal. If the valve is stuck or missing, the case may be very difficult to open after altitude changes.

Storm Cases vs Standard Peli Cases: Which Should You Buy?

If weight is a priority — you are flying frequently, carrying the case any distance, or working within airline weight limits — the Storm range has a meaningful advantage. The lighter construction makes a noticeable difference on larger cases in particular, where the weight of the case itself can become significant relative to its contents.

If you prioritise a very positive, secure latch feel and intend to stack cases or subject them to very heavy loads, the classic Peli double-throw latch has the edge. Both ranges are equally waterproof and crush-resistant — the differences are primarily ergonomic. In the surplus market, availability varies; if you find a good example of either range at the right price in the right size, the practical performance difference is unlikely to matter for most applications.

Frequently Asked Questions

Are Peli Storm cases waterproof to the same standard as regular Peli cases?

Yes. All Peli Storm cases share the same IP67 waterproof rating as the classic Peli range — they can be submerged to one metre depth for 30 minutes without water ingress. The O-ring seal design and automatic pressure equalisation valve are identical across both ranges. The lighter HPX construction of Storm cases does not compromise the waterproofing in any way.

What is the difference between a Peli Storm case and an iM case?

They are the same product. Peli refers to the range as ‘Peli Storm’ in the UK and European market and as ‘iM’ (the model numbering prefix) in some other markets, including the United States where the brand trades as Pelican. You may see both designations in listings and descriptions for the same cases — iM2200, iM2750, and so on are all Storm series cases.

Where do used Peli Storm cases come from?

The majority of surplus Peli Storm cases in the UK come from military disposal — primarily UK and US armed forces equipment that has been decommissioned as part of routine asset management. Cases also enter the surplus market from professional broadcast, film, and production companies upgrading or clearing equipment. Military-sourced cases are typically in solid functional condition, often having been stored more than actively used.

Can I replace the foam in a used Peli Storm case?

Yes, easily. Replacement foam sets — including pick-and-pluck foam inserts — are available for all major Peli Storm models from Peli’s UK distributors and third-party suppliers. Prices range from around £20 to £60 depending on case size. Many buyers prefer to source foam separately and cut it to their own specification, which gives a more precise fit for specific equipment. Open-cell foam in standard sheet sizes is available from upholstery suppliers at very low cost.
