Question: Do you have to tie knots so they stay around the stakes?
Document: Product came as advertised. Fairly easy to set up... doesnt come with stakes so make sure you pick a location with trees or heavy rocks to tie down to. Ropes are very strong very easy to tighten.Folds up small into one of those ENO Bags.
Solid investment for anyone using the ENO hammock system. Has an excellent balance between footprint and coverage, better than that of ENO's other rain flies (Dryfly and Fastfly). I like how it is a completely separate unit as well; this allows for it to be more than just a rain fly for your tent. I have used it several times for a sheltered work station and is much better than hanging around in a tent for the weather to pass.Rolls up smaller than a Nalgene bottle and requires 4 stakes.
bought this on amazon after someone gave me the doublenest hammock as a gift. the rain tarp is easy to set up - and is so much easier to get into the hammock than other rain tarps that have a tie out in the middle (6 tie outs vs 4).amazon, as always - was a pleasure to deal with.
This product is great. The coverage is perfect and the materials are quality. The big issue that I have with this product is that the tie down cord is dark in color and not reflective, which makes for an extreme trip hazard not only at night but during the day as well.I have since purchased some reflective paracord which has solved the problem.With the exception if the cord, it's worth every penny.
I bought the olive colored and in the picture the sack is attached to to fly but the one I got it is separate and also it does not come with any stakes to stake it to the ground so you will need to get some if you don't have any. Other than that it is a very well made  nice rain fly
This rain fly was a breeze to set up and made a comfortable little nest when I had my ENO hammock and tent footprint set up with it. The only reason I have given this 4 stars and not 5 is that I haven't seen its performance in rain yet. Great for windbreak and privacy purposes though!UPDATE: In the wind, it can have a tenancy to loosen up and start to sag - I've had to re-tie it when I get up in the morning.
I really like this fly, but I think I will eventually get a different one for a different style of camping. I like the design and it's good for what it's designed for. I use this with a hammock and if it rains really hard, you can still get wet. The cold air will get right underneath it too. VERY sturdy and I love the tie pulls. If mine broke I would get another.
I used the rain fly the first weekend i had it. I had gone on a camping trip with some friends and there was a 30% chance of rain. Well they got that one wrong, it rained for 3 hours and then the rest of the night on and off. The rain fly was easy to set up and adjust, and really kept me dry the whole night. 2 thumbs up! The only problem i see is that it doesnt come with its own stakes.
At first I thought it might be too small to keep rain off but it fits my favorite camping spot perfectly so I'll stick with it. I really like the tensioning system that doesn't use knots.
I purchased this tarp, along with the Eno single hammock and bug net, to deploy while working in the African bush. It's lightweight, durable and provides great protection. I'd recommend buying the MSR Groundhog stakes, along with the Nite Ize C9S Figure 9 Carabiners, for fast, secure setup. Whether there's wind, rain, or even sideways wind & rain, this tarp has yet to fail me.
