So where do you buy this stuff from?
Is it for your ski jackets? or for thermal/base layers?
I have always just used hand wash soap liquid (delicates stuff) for under layers.
This stuff is for my Jacket and Sallopets
I bought it from Decathlon sports store, although i have also seen it online. Cost about £5 for a bottle which is enough for 3 washes, maximum 2 items per wash.
