Tougher Than the Elements. Designed for Life’s Extremes.


The Seahorse SE-300 isn’t just another hard case—it’s a fortress for your gear, engineered to withstand water, dust, impacts, and extreme conditions. Whether you're a professional on the move, an adventurer braving the unknown, or a gear enthusiast protecting delicate equipment, this case delivers next-level durability and security.

Why This Case Stands Out:
We built the SE-300 for those who refuse to compromise on protection. Designed to handle anything—from rugged terrain to unpredictable weather—this case is watertight, airtight, crush-resistant, and impact-proof.

From camera gear and electronics to emergency tools and tactical equipment, the shock-absorbent interior and customizable foam insert provide maximum security for whatever matters most.

Key Features That Make a Difference:
IP67 Waterproof & Airtight Seal
Submersible up to 3 feet, this case keeps moisture, dust, and debris out—ensuring your gear stays dry and protected in any environment.

High-Impact Polycarbonate Shell
Built to handle drops, pressure, and crushing forces, the SE-300 absorbs shock and prevents damage to fragile equipment.

Automatic Pressure Purge System
Traveling at high altitudes? The built-in pressure equalization valve prevents vacuum lock, making the case ideal for air travel and extreme altitude changes.

Lockable & Secure
With a twist-lock safety latch and carabiner loop, you can secure your case with ease. Rustproof hinges ensure long-term durability, even in the harshest conditions.

What’s in the Box:

  • Seahorse SE-300 Hard Case
  • Shock-Absorbent Foam Insert for customizable protection
  • Removable Mesh Lid Web for organized storage
  • Lifetime Guarantee—because we stand behind our cases for life

Why Buy Now?
Your gear deserves the best protection—don’t wait until it’s too late. Whether you're safeguarding sensitive electronics, tactical tools, or professional equipment, the Seahorse SE-300 is trusted by professionals worldwide.
