Yes just as any hat. I put my clothes with cold water Tide. I then put the dryer on air dry. I have had no problem.

What percent copper does the protective lining have?

If you read the contents on the hat, it reads that the interior liner has 40% silver, 50% bamboo, and 10% spandex. (do not see copper listed on there).

When will grey hat be in stock?

Hi T/D, we have more grey beanies landing sometime in August. I will reply here again once they are available so you know :)

is delivery time really 1-2 months?

Once a tracking number is created it is in the US and on the way to the Amazon warehouse. This is when Amazon can say it is available in 1-2 months to be super safe, as it can at times take 2 weeks+ sometimes to check in once it gets to them (depending on time of year). This particular shipment is only a few days from the warehouse, so hoping they are closer to 2-3 weeks (tops) until being able to be shipped to customers. If you check in every few days it will change suddenly when they clear from 1-2 months to 3 days! Hope this helps :)
