I sort of wish I hadn't had the option, but when I was over at my in-laws today making a video, I had the opportunity to weigh all my gear.
The tarp is made of 70D silnylon......It comes in at a hefty 3lbs 9oz
Not exactly what I was hoping to see. So far, though, I love it! It seems to be a great tarp and it should suit me fine in just about any situation/weather I will come across on my adventures.
If it was made of 30D, it would weigh in at around half that, so for those with the $, go for it.
I just made it retractable which also adds to that weight. Check it out.
