Alvin W.wrote a review of Eagles Nest Outfitters SlapStrap Suspension Strap - 25mm - Pair on June 7, 2016
Familiarity: I've used it once or twice and have initial impressions
I purchased these with a hammock. They are great for the flexibility of hanging your hammock, but since I am a heavier hammock user the straps tend to have a lot of stretch. For myself, I am going to try a strap system constructed of another material.
