Double the length, double the fun! This shackle is 20" when the loop is closed and 40" long when it is open. Why do you want this in your Recovery Gear Bag? 
The length of this soft shackle allows you to "double" it up by looping it around your connection point. This will nearly double the strength of the soft shackle.
Use its extra length for more maneuvering room (under stuck rigs) to get your kinetic rope or winch line attached and ready for a pull.
Yankum added a 36" chafe sleeve to "double up" the abrasion protection.
HMPE synthetic fiber is pre-coated for UV, water, and abrasion protection so this soft-shackle will last a very long time as long as you don't swear at it too much, we can't protect its feelings with a coating.
