About Extreme Cases
Large enough to supply militaries across Europe. Small enough that our managing director will take your calls. With 57+ years staff experience crafting custom cases, we'll guide you to the perfect solution for your project specs.
The Story of Extreme Cases
I'm Mark Brown, Founder of Extreme-Cases
If you ask most of our staff, they'd probably guess that I've been in the rugged cases industry since the age of the dinosaurs. And while it hasn't been quite that long, I HAVE been engineering extreme protective cases since 1979 - longer than most of our team have been alive.
I founded Extreme Cases in 2009, as a boutique manufacturer built by engineers, for engineers. From the beginning, we've specialised in crafting unique solutions to match unique project specs - with innovative features, fast turnaround times, and an attention to detail that you won't find with larger rugged case companies.
Trusted by the MoD, the Bundeswehr... and Avengers: Age of Ultron
Over the years, we've been trusted to work on both high profile and classified projects... a few that we're allowed to talk about include a deployable post office for the MoD, the "Smart Beam mission planning system" with GDUK, and a decompression chamber for a super yacht.
Sometimes our products show up in unexpected places. A few of our youngers engineers got a kick out of it when they noticed one of our custom transit cases featured onscreen in Avengers: Age of Ultron!
Indestructible Cases for Mission-Critical Gear
Leave the off-the-shelf cases to hobbyists and weekend warriors. Serious projects deserve serious, custom gear.
At Extreme-Cases, rugged, military-grade protective cases and containers are only a starting point. Our sweet spot is engineering bespoke solutions that protect sensitive equipment from extreme environments. On time, on budget, and on spec.
