The compression bags are plastic. Another message had mentioned how bulky fleece items were to pack so I suggested the compression bags! The bags are not made of bulky fleece!!

I agree that you get a few wrinkles but it's worth it for the space you save.

Take the items that have wrinkled and hang them in the hotel bathroom, turn the hot water on full force and create your own steam room. Then turn the water off and leave the door shut. After awhile, you'll find that many of the wrinkles have disappeared!
