Tactical meets BDSM: Design concept originally was to find a way to give the feeling of being tied down / stretched out wide, but with more comfort and less body stress to allow the positions to be done longer. Many enjoy the tension of a stretched position, but without much give in the materials, it tends to cause circulation issues quickly. So with these bungee tension straps the intent is give that being stretched or held down feeling while having some flex/give before maxing out length.
Heavy duty 1" tubular webbing is used with 4 shockcord strands inside to give the tension effect. Although not made for full human load bearing, they are made for general hard use and not to be confused with cheap polyester BDSM products.

Another problem these straps try and solve is that usually not a lot of rope is needed to connect bondage, yet 15 feet is considered a standard short rope length.
The loop size allows lots of versatility to adjust the overall length and security considerations. For example connecting sides with knots or using carabiners or even wrapping back around to the connection point to make them "half size". Dialing in the length is critical to achieving the desired tension effect. Check out more pictures at http://www.discerningspecialist.com/bdsm-gear/restraints/48-dsg-bungee-tension-straps

For secondary uses they also happen to be handy with anal hooks :)

To clarify this listing is just for 1 pair (2) tension straps and no other items.
