According to test data supplied by the manufacturer, Fifth Ridge Pty Ltd, this fabric’s TPU membrane has pores measured at approximately 0.16 microns at maximum distribution (third-party capillary flow porometry, Galwick fluid) — well below that range, which is why the fabric can be used as a particle barrier. The zippered closure encloses the doona on all sides. We have not independently conducted this testing; the figures are reproduced in good faith from the manufacturer.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\n\u003cdetails class=\"dmas-acc\"\u003e\u003csummary\u003e\u003cspan class=\"dmas-summary-head\"\u003eMaterials \u0026amp; specifications\u003c\/span\u003e\u003cspan class=\"dmas-chev\" aria-hidden=\"true\"\u003e\u003c\/span\u003e\u003c\/summary\u003e\u003cdiv class=\"dmas-acc__body\"\u003e\u003cdiv class=\"dmas-table-wrap\"\u003e\u003ctable class=\"dmas-table\"\u003e\n\u003ccaption class=\"dmas-visually-hidden\"\u003eMaterials and testing specifications\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eFabric outer\u003c\/th\u003e\n\u003ctd\u003e90gsm polyester knitted jersey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eLining\u003c\/th\u003e\n\u003ctd\u003e0.2mm microporous TPU (thermoplastic polyurethane) waterproof membrane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePore size\u003c\/th\u003e\n\u003ctd\u003eApproximately 0.16 microns at maximum distribution (capillary flow porometry, Galwick fluid).
