Hello, I'm looking for an ultralight float tube. I want to carry the tube deflated in my backpack into high mountain lakes. What would you guys suggest as being the best option? The wilderness lite tube seems to be the best thing I've come across. Any others out there that are worth looking into? I was also thinking that a packraft might be a good way to go. I want to be able to use the raft with fins though, so I'm not sure how that would work. Can packrafts get anywhere near as light as the ultralight tubes? Thanks!
