What People Are Saying About PinnedDown™

  • "TSA is not the best with care of sensitive items. I hated opening up the weapons cases to see a separated brittle foam mess. I'm definitely behind this secure lock in system. securing and protecting your expensive 2A assets beauty has got me interested."

    —Paul R, Army Veteran, HoldOver Systems Community

  • "Retired Marine Corps veteran here and I can' tell you enough how frustrating it is to have so many cases piled up for "custom" layouts. I'm so pumped for you to release your products to have a completely modular all in one system! Thanks for making the shooting world that much more enjoyable!"

    —Joshua D, Marine Veteran, HoldOver Systems Community

  • "I've spent 8 years serving in the navy and relied on every type of protective case imaginable. the last thing we ever wanted was a foam-lined case that absorbed water, stayed soaked, and put our equipment and ultimately our mission at risk."

    —Moses J, Navy Veteran, HoldOver Systems Community

  • “I’m ready for it man, I just spent about $600 On foam for two cases.”

    —Robert F, Air Force Veteran, HoldOver Systems Community

  • "Foam is definitely the cheapest option for the inside of a protective case. Excited to see this thing launch."

    —Tim H, HoldOver Systems Community

  • "As a current service member, I know how bad the foam issue is. about time someone is fixing it!"

    —Joshua S, Army Veteran, HoldOver Systems Community

  • “Replacing foam every time i make a change to my attachments is such a waste of time. a one & done setup that will handle whatever loadout i place in it? that i can change in seconds without replacing inserts every time? saves time, saves money. Sounds like a no brainer to me.”

Frequently Asked Questions.

  • Many current solutions still depend on foam as part of the system. They may make foam easier to arrange or replace, but foam remains the foundation.

    HoldOver™ takes a different approach. It's being developed as a foam free protective case system designed to be reconfigured instead of repeatedly cut, replaced, or thrown away.

    The goal is not to make foam slightly more tolerable. The goal is to make foam unnecessary.

  • HoldOver™ is being built for serious users who rely on protective cases for valuable, mission relevant, or frequently changing equipment.

    That includes firearm owners, tactical users, competitive shooters, drone operators, photographers, medical users, field technicians, and anyone who needs protective storage that can adapt as equipment changes.

  • Not yet. HoldOver™ is currently preparing for launch. We're using this stage to finalize development, gather early interest, and keep future customers updated as the product moves closer to availability.

    Join early access to follow the build and be first when we launch.

  • Yes. We've filed a U.S. non provisional utility application for HoldOver™.

    What matters to you: this is not another foam insert. It's an engineered system that's protected while we build it.

  • Yes. HoldOver™ is being designed to protect valuable gear while giving users more flexibility than traditional foam.

    The system is being developed around secure fit, reconfigurability, cleanability, and long term usability. Because it doesn't rely on disposable foam, your setup stays effective for years instead of months.

  • HoldOver™ is being designed with real world use in mind. That includes rugged handling, transport, sealing, and field readiness.

    Final specifications, testing results, warranty details, and shipping information will be released closer to launch.
