AceCamp Glow in the dark rope increases the security because you reduce the risk to trip over it or run it. The material recharges quickly by sunlight and artificial light. The lines take on virtually no water because they are made of polypropylene. This material is very resistant to tearing. The lines are available in three strengths and three lengths. There is no point, when already using glowing rope, but you might like to add extra awesomeness with glow in the dark tent pegs.
