Rated 5 out of 5 by from Like runway lights I bought this rope primarily to hang my food. After hundreds of nights in the backcountry, there have been occassions where I went to go hang my food back up in the dark only to have a little problem finding the spot I threw the rope earlier in the day (that 50-100 yds. looked simple in the daylight). I bought the blue rope and it works amazingly well when my petzl light hits it. It looked like a pair of runway lights hanging from the tree. I'm going to buy another one to replace my clothes line for those dark trips back to camp. In the two weeks I was out it seemed durable enough, but a few more trips will really tell the story.

Rated 5 out of 5 by from Best cord you can buy. I have been using this reflective cord for several years now, and wouldn't consider camping without it. In addition to using it for bear bagging, I also use it for the guylines on all my tents and tarps. I use the orange color for the guylines, as even in the daylight, no one can say they didn't see it. I use the blue color for the ridgeline on my tarps, so I automatically know which corner is for the ridgeline and which ones are for the guylines. It makes setting up in the rain so much quicker. Friends who go camping with me quickly see the utility of this cord and purchase some as soon as they get back to town. In the attached photo, the flash from the camera illuminated the guylines, even in daylight.

Rated 5 out of 5 by from Great for Bear Bagging Used it two for my bear bag two weeks ago when I went on a weekend backpacking trip. I had read other reviews that it made it really easy to find your bearbag at night if necessary. I hung my bag about 75 feet away on a tree that was only just visible from my tent and waited till nightfall. After it got dark I scanned the woods with my flashlight from my tent and was able to clearly pick out where my bagging line was. It stood out as white on a black background. Well worth the money, I was considering buying a cheaper, similar version but now I am happy I went with this one.

Rated 5 out of 5 by from Great reflective cord I purchased this with the intention of using it for my tent fly, but elected to use a thinner cord instead. Since I already had it on hand I decided to use it for my bear bag / utility (clothesline, etc) line while backpacking. I just returned from a backpacking trip where this was used as my bear bag line. This cord is strong and lightweight and held up well to being pulled across branches. Best of all it is reflective which made it very easy to string and retrieve in the dark. It was 3x as expensive as the plain utility line, but well worth the price.

Rated 5 out of 5 by from As useful as your flashlight I primarly use this cord to hang my bear bag. Having been stuck searching for my bear bag in the dark before, I knew that something reflective would be very helpful. Broadcast your flashlight or headlamp back and forth across the area and this cord will call out to you. I also use small lengths of it as lanyards on my knife, multitool, and flashlight. If I drop them in the brush I can find them much easier, especially with a flashlight. Be sure and melt the cut ends with a lighter to prevent fraying.

Rated 5 out of 5 by from Perfect for bear bagging I used this cord on the A.T. for bear bagging and for tent stakes. It's extremely reflective and is effortless to find at night. I still have it, and still use it.

Rated 5 out of 5 by from BW Blue Niteline I use the Niteline for the guy lines to my tent and hammock, and love it, often at night the lines are impossible to see and everyone is tripping over them this makes it so people are not, saves torn equipment, and injuries from falls and trips.
