Bags: You will likely never need to wash your Datsusara bag as hemp stays naturally clean due to it's antimicrobial and breathing properties. In case you do we recommend you only hand wash in cold water (cold water prevents material shrinkage) and line dry. It is possible to machine wash the bags but it's tricky and we cannot warranty against damage from machine washing. As for the "Nasty bags" (which are synthetic) we recommend washing them however you like but line dry.
Apparel: For apparel you can wash however you want. But don't use any bleach as it weakens the hemp, and do keep in mind the hotter the water and dryer setting the more things will shrink. For new combat gis we strongly recommend machine washing at least 2-3 times to prevent shedding of the material which occurs naturally with our 100% hemp gis.
