Mountain Laurel Designs. I chose this combination precisely because it's more open air. I really don't want to close myself off from nature anymore than necessary. That is, after all, why I'm out there. Most of my hiking will be here in Tennessee where it gets pretty hot and humid, and this open shelter will be good for that. In the middle of summer there are times when any breath of air at all is welcome. This tarp can also be set closer to the ground for better protection, but eventually I'll also want to get a more enclosed pyramid-type tarp for winter and bad weather use (like MLD's DuoMid tent).
