Large Adventure First Aid Kit – Class B

When conditions get tougher, your first aid kit should too.

Our Large Waterproof, Indestructible Adventure First Aid Kit is built for demanding outdoor use and higher-risk environments. Whether you’re outfitting a jobsite, heading deep off-road, or preparing for extended trips, this kit delivers expanded coverage and durability you can rely on.

Part of our WIAFAK line, this kit was designed by people who actually use their gear. We saw what was missing from typical outdoor and jobsite kits and built something better—stronger protection, smarter contents, and more capacity where it counts.

This is a Class B ANSI/ISEA Z308.1 compliant first aid kit, making it ideal for more hazardous workplaces and crews operating in rugged outdoor conditions.

The case is made in Texas and built to take a beating. It resists impact, dust, and water to keep your supplies clean, dry, and ready. We selected this rugged case after real-world testing because performance matters when it counts.

Bottom line: when the environment is unpredictable, this kit gives you the confidence that your gear will hold up.
