Never used 4p lightweight baker style shelter great for backcountry trips. Woodland camo coated nylon outside, reflective aluminum coating inside. Zippered door option. I have and use the mini 1-1/2p version and it's absolutely fantastic...I'm using stock photos as I haven't used this yet. Weighs 3-1/2 lbs Again this one is in woodland camo. $300 shipped Thanks John
