I have the Hexa Pro Tarp as well. Was thinking about getting the Inner Roof but wanted to see real-life photos of it in use as well as some reviews. Those are pretty much non-existent. Could you post photos of the actual Inner Roof in place? I am curious to how it is put together along with the Hexa Pro Tarp.
The only photo I have that shows the inner roof is the night shot in my previous post. It shows the tarp with the inner roof and the fire pit underneath. I didn't take many pics of the inner roof because it was pretty nondescript, and I've since taken down the tarp. The inner roof is grey in color and blends in with the Evo Pro tarp to create a seem less roof line. I attached the manual so you can see the setup instructions. My Evo Pro tarp was already setup so I just had to add on the straps to the poles and then connect the inner roof to the straps (see manual). Tighten up the straps and then attach the sides which use bungee cords. The Evo Pro tarp comes with two 3 meter cords to secure the sides of the tarp, one for each side. I like the sides of the tarp raised up for easier entry, so I use 180 cm tarp poles to raise the sides. The manual recommends if raising the sides of the tarp, to secure the side tarp poles with two tie down straps. Normally I would use one strap to secure the tarp pole on the side, but in a wind the pole does move around. Since I putting a fire pit under the tarp I wanted everything secure in case the wind picks up. The first pic in my previous post shows the side tied down with one cord. I didn't have the inner tarp setup in that pic. In the last pic, I have two cords securing the side tarp pole. After I had it all setup, the Evo Pro tarp with the Inner Roof was very secure. It held up fine during a windy and rainy afternoon. I attached a photo I found online on securing the tarp to the poles to prevent it from blowing off the poles in windy weather. I did that to the main poles but not the side poles -- next time!
My impressions are it works as advertised. I had a couple camp fires under the tarp, one night it rained so that was pretty nice to sit outside by the fire and still be protected from the rain. The fabric feels like a heavy cotton material, not stiff like a canvas. It looks like it will hold up well. I wasn't concerned about it igniting The manual shows pictures (I don't ready Japanese) that says to just put one fire pit under the inner roof, not two. I lit a charcoal chimney sitting on the fire pit under the tarp. Heat wise it was fine but the charcoal smoke didn't blow away as quickly when it was starting up. The Evo Pro tarp is expensive. The Inner Roof is priced fairly reasonable considering it's Snow Peak, and it enables you to use the tarp and have a camp fire even in inclement weather. I'm very happy with the purchase. Next time I setup the tarp I'll take more pics.
