No, they don't fold up, but these guys make great lightweight boats. I have a modified carbon/kevlar haystack that weighs 13lbs. Probably not going to take them with you flying, but for paddling trips with some carries they are great. I use mine mainly for pack in or paddling trips to Brook Trout ponds and just paddling around the local lakes. I can easily go for a few days in mine living quite well. The 12' Skylight would make a great paddle in deer hunting boat.
