Unless it's made waterproof through some sorta waxing method a non waterproof tent isn't the best of ideas.
I love the color of the fabric and seems better suited to being used in a shirt or stretchy bandana or something like; though, again, if it's waxed it may be the best damn tent ever made, though I'm not familiar with waxing cloth and how they'd handle in field like settings and such it just seems like it'd be a good solution and keep the unit lightweight and manageable.
