The hammock and tarp weight about 2.5lbs and remove the need for a sleeping pad. I have not tried it out yet. Wanted to see if I could get my dog in it with me comfortably. SO i ws looking for something for summer. Normally I camp with a SMD tarp but because I live n Texas there are a lot of bugs in the summer time. If I like it I was wondering if anyone has used reflective as a sleep pad to stay warm when the weather is cooler or cold. It weighs about an oz a foot
