So I was out Monday night and slept through a nice steady rain. My cuben fiber tarp kept me dry, and the sounds of the rain had me hard asleep. After I packed everything up I removed the stakes and shook the tarp a bit to get the rain drops still remaining off of it. It had stopped raining at this point. As I began to roll the tarp into the mesh skins I noticed it felt a lot different than normal. As I untied it from the tree I noticed it was a lot heavier. Suddenly my 6 oz. cuben tarp weighed about 2lbs! It was like the material itself had absorbed the rain?
I set it up over my lunch break, during my hike, and it dried out quickly with a little sunshine and light breeze. I'm still trying to figure why it was so heavy. Anyone else experience something like this? I've had my silnylon tarp absorb a bit of water, but not get noticeably heavier as a result. This was very noticeable.
