Toss in the wash with cold water. Air dry. Boom.
I want to love it
"I have another Rothy’s bag that I really like and I’ve had for years. I want to love this one but there are a couple things to note. I wish the straps were more adjustable and the snap to kepp it closed does not stay closed. I think the snap idea is nice but just not strong enough to stay snapped. I may just need to adjust how I’ll packing it but if I add my camera, it will almost certainly not stay closed."
