Dapre laWikiPedia: Cordura is a collection of synthetic fiber-based fabric technologies used in a wide array of products including luggage, backpacks, trousers, military wear and performance apparel. Cordura fabrics are usually made of nylon, but can be a blend of nylon with cotton or other natural fibers.

30D Cordura® is woven by 30 denier nylon and 66 Cordura® yarn (Normally, nylon fabric is woven by nylon 6.) High-tenacity nylon fabric is stronger and approximate 2 times abrasion resistance level than standard nylon. There are two regular versions of 30D Cordura®: Sil/PU and Sil/Sil version depending upon its purpose and use.

Sil/Sil
Nylon 30D segondè -tenasite ak silikone kouvwi sou tou de figi yo. Silisyòm fekondasyon travay vrèman byen ak twal ki lejè kòm li amelyore fòs chire twal, rezistans fwotman ak kapasite pake. Twal silikonize gen yon mezi pwòp tèt ou -geri lè yo twou.

Sil/PU
Nylon 30D segondè -tenasite ak Silikon enpreye sou figi deyò a ak yon kouch an poliyiretàn (PU) sou andedan an. Li gen yon rezistans dlo ki depase 4,000mm. Eksteryè Silicone a travay vrèman byen pou koule dlo ak pou kreye yon sifas ki glise pou anbalaj fasil. Kouch PU sou andedan an amelyore evalyasyon waterhead la epi li pèmèt tep sele kouti kole.

All of our Cordura ®light dry sack are made from the Sil/PU version as the PU coating provides better water resistance performance.
