I do know of a couple of people who washed their Altura jackets(not the night vision version though) weekly with non bio and then noticed it wasn't waterproof any more. I try not to wash mine!
Turn the washing machine to 30 degrees c, zip up all the zips, fasten all the velco, use non bio washing powder. I wash it by itself, so it wont get damaged by anything else in the waching machine. Then hang it up and leave to dry.
what do i use to wash?...getting a tad smelly???
