Handy rubber bands for many things.
I thought first it is a toy, but I love them, they are perfect to fix underquilts under a hammock or to have one side of the tarp in the "british elastic" configuration.
Very quick to add, adjust and remove, I love them.
Works as described. God product to a affordable price.
Seems OK, but I have to figure out the right use for these yet since I am new to hammocks :)
