  • Mission-Critical Waterproofing: Engineering Tactical and SAR Dry Bags for Zero-Failure Scenarios

    When the contents of a dry bag are a $15,000 encrypted radio, a trauma kit, or a team's only communications link, "water-resistant" is not a useful product specification. This whitepaper works through three failure scenarios specific to tactical and SAR dry bag applications—maritime amphibious insertion under surf stress, sub-zero alpine SAR deployment where PVC shatters, and night operations where standard commercial hardware creates optical signature risk. For each scenario it covers the construction failure mode in detail and the manufacturing specifications that address it: airtight mechanical zipper closures, 840D TPU with tested cold-weather flexibility, RF-welded load-bearing hardware attachment, and OPSEC-compliant non-reflective hardware selection.

  • Custom Dry Bags: Materials, Sizes and Branding Options

    Sealock is a custom dry bag manufacturer producing OEM and private-label waterproof bags for outdoor brands, retailers, and promotional buyers. A custom dry bag is defined by three decisions — the material it is built from, the size it is cut to, and how a brand's identity is applied to it — and getting each right is what turns a generic bag into a product that fits a market and survives real use. This walks through every one of those choices, with the practical details buyers most often get wrong.

  • What is the difference between a dry bag and a waterproof bag?

    In summary, while both dry bags and waterproof bags offer water-resistant protection for belongings, dry bags are specifically designed for activities where complete waterproofing and submersion protection are necessary, while waterproof bags may offer a more versatile and everyday solution with varying degrees of water resistance.
