I bought the Walmart Outdoor 5x7 trap last year as an emergency hiking tarp for my day hikes. Every now and then I see posts about the tarp asking how well it would work as a tarp for a hammock so I thought I would set up a hammock with the tarp and see how well it worked.
Sold by Walmart about $10
Outdoor Products 5Wx7L tarp...made in China
Manufacture says it weights 12 oz but mine weights 9 oz with stuff sack
Made of water resistant urethane coated nylon
Comes with 4.5” x7”stuff sack. Stuff sack has mesh front and back to save weight and has a hanging loop. Hard to get back into stuff sack after removing.
Tarp I got is blue. Did not see any other colors.
Comes with brass grommets in each corner and one in the middle of each side. Seams are sewn all the way around the tarp.
As the ENO DN is a very popular hammock I decided to use it for my test. I used an a Single Line Tarp Ridge Line - Dutch Edition with Dutchware for hanging the tarp.
I tried to use full biners with the tarp and found the grommet holes are too small. Micro Biners work just fine.
I set up the tarp as a rectangular tarp and as a Diamond. Either way it did not cover the hammock length wise and offered minimum side protection.
Bottom line....if it rains, you will get wet. If you have a down sized child's hammock then it might offer enough protection.
The only way I would use this tarp is if the weather was nice and I just need something to keep the sun off my head.
Sewing 2 of these tarps together might make it big enough to offer enough protection but you would have to overlap the seams as there will be grommets in the way.
IMO, there are much better tarp options out there.
