Those soft envelope/bags for mailing clothing?

Question

I know you can get from the post office those priority mail boxes, or the cardboard envelopes that are bigger.... I've seen the soft packs that seal that people use to send clothing, or things that arent easily damaged- any idea what those are called or how to get them- I cant find it on the Post Office website.....?

Answer 1

You can find them on the website, they are called "Priority Mail Envelope Tyvek".  Look under "Products: Priority Mail", they are the 6th item shown.  They don't look like bags on the page but if you click on the item, it states that it is durable, and water resistant.  I'm 99% positive this is what you're looking for.
