Custom ground cloths, called tent footprints, are available for most Mountain Hardwear tents. These waterproof footprints protect tent floors from damage and prolong tent life by adding a layer between the tent floor and the ground.
"Here's a no brainer: buy this with the tent!"
I couldn't find the weight of this footprint when I was looking, so I'm going to let you in on a little secret and tell you that mine weighs 159 grams, less a little bit of dirt from the first trip that I haven't been bothered to scrub off. Sorry America, most of the world uses metric, google it if you need to.Yes, the Supermega UL is ultralight and therefore not-so-robust, and needs a footprint if you're going to camp anywhere other than the plush, manicured lawns of your local golf course. I really hope you'll need a footprint... Go on. Do it.
