Dry Bag Academy

The Academy collects everything we publish on how waterproof carry actually works: what makes a seam fail, how hydrostatic head numbers are produced, why IPX7 is not the same as diving, how salt and UV shorten a TPU film’s life, and what to check before signing off a production sample. Each path below moves from first principles to the numbers you put in a specification sheet.

Material comes from production experience since 2014 in an SGS-verified 4,950 m2 facility in Fujian, China, with 7 lines and 149 machines running 200,000 pieces a month. Where a claim needs a standard it is cited against ISO, ASTM or IEC methods so you can repeat the test independently, and water-condition and safety figures are checked against NOAA.
