Jacket needed... waterproof and very breathable

from the care label:
for optimum performance frequent washing is required.
machine wash warm with liqid detergent secure all zippers and closures rinse twice, hang dry steam iron warm to rejuvenate water repellent finish, do not use bleach, do not use fabric softner. do not dry clean.

it say the same inside my E-vent montane waterproof.

you should always use non-bio to wash your technical fabrics.

Thanks for the info.

Naturally I use non-bio for everything (being a tree-hugging type). Ecover all the way.
