So I posted this here in General because these can be used for pretty much every part of hammocking. Ok so understanding that their strength is not rated for hanging your hammock; these little things are awesome to have. I found them at AutoZone at the register for $4.99. They are super small and are great for hanging your UQs and various other things. So if your a fan of the S-biner then here is a place you can get the super mini version for cheap.
They are also decent for just putting keys on too...But who needs Keys on a hike?
