Skiing & Snowboard Cases: Move the Gear Through Snow
Skiers and boarders carry goggles, an avalanche beacon and bindings that are precise and cold-sensitive. A ski case fixes the goggles, isolates the beacon, absorbs shock and survives being carried through snow. This guide covers goggle protection, beacon isolation, cold and slope use.

Case Gasket and O-Ring Materials: EPDM, Silicone and Closed-Cell Foam Compared
The seal is the part that makes an IP rating real, and the part most often specified by habit rather than by environment. EPDM, silicone and closed-cell foam differ in compression set, temperature range and chemical resistance, and the right choice depends on what the case will meet more than on what the catalogue lists.

Case Latch and Hardware Materials: Nylon, Stainless Steel and Aluminium Compared
The shell takes the impact, but the latches, hinges and handles decide whether the case opens after it. Over-centre latches work by geometry rather than by force, and the material they are made from sets their fatigue life, their corrosion behaviour and how they feel after a few thousand cycles.

Pressure Equalisation Valves on Protective Cases: What They Do and When You Need One
A pressure equalisation valve lets a sealed case breathe. It passes gas through a hydrophobic microporous membrane while blocking liquid water, which solves two opposite problems at once: vacuum lock after a flight, where internal pressure holds the lid shut, and over-pressure, where a case sealed at altitude bulges at sea level.

ESD and Anti-Static Protective Cases: Surface Resistivity and When It Matters
An anti-static case is specified by a number, not an adjective. The industry works in surface resistivity bands: conductive, dissipative and insulative, with the dissipative band being the target for most electronics handling. Under ANSI/ESD S20.20 the dissipative band runs from 1x10^4 to below 1x10^11 ohms; IEC 61340-5-1 sets it from 1x10^5 to 1x10^11 ohms.

Watch Storage Cases: What Actually Protects a Collection
A watch does not usually fail from impact. It fails slowly, from humidity cycling behind the crystal, from UV fading a dial or a strap, from magnetisation, and from a strap stored under constant bend. A storage case should address those four mechanisms before it addresses drops.

Fishing and Marine Gear Cases: Salt, Hooks and Washdown
Marine duty is harder on a case than almost any other environment, because the threats are simultaneous: salt spray attacks hardware, grit abrades seals, sharp hooks and blades puncture linings, and everything is wet when you pack it. The case has to seal, drain, survive a washdown and not corrode shut.

Musical Instrument Cases: Protecting Wood, Brass and Electronics
A guitar, a trumpet and a stage keyboard are damaged by different things. Wood moves with humidity and cracks; brass dents and corrodes at the contact points; electronics fail from impact and from vibration. One case specification does not serve all three, and the differences are in the interior rather than the shell.

Power Tool and Lithium Battery Cases: Transport Rules and Case Design
Shipping lithium batteries is regulated as dangerous goods, and the rules have teeth. Under IATA DGR, lithium-ion cells and batteries must pass the UN38.3 test series, and from the 2026 edition a state-of-charge limit of 30 percent applies to cells shipped on their own and to spares packed with equipment.

How to Test a Waterproof Case on Delivery: An Incoming Inspection Method
A waterproof claim is a statement about a sample, tested once, under controlled conditions. Incoming inspection turns it into a statement about the cases in front of you. The method is not complicated, and most of it can be done in a few minutes per case with a torch, a cloth and a basin.

Pick-and-Pluck Foam: How to Cut a Cavity That Actually Holds
Pick-and-pluck foam is a grid of pre-scored cubes you tear out by hand. It is the fastest way to a custom cavity and the easiest way to get one wrong - most DIY cavities are too large, too shallow, or cut in a way that leaves the contents resting on the case floor rather than supported by the walls.

Case Stackability and Pallet Planning: Fitting More Into a Container
Freight cost is charged on volume or on weight, whichever binds first. Stackability is the variable that decides which. Cases that stack without crushing, that share a footprint with a standard pallet, and that interlock rather than slide are the difference between a container that cubes out and one that leaves a third of its volume empty.
