My RR Lynx under-quilt has rubber bands that connect the lower end to the hammock via mini-carabiners.
I replaced one recently using the extra band that Brandon provides when you buy the under-quilt. Glad I brought it along on my canoe trip. Now I need to replace the other one.

Obviously they are just heavy rubber bands. I’m not going to order something from the States that costs $1.00.

Has anyone made their own from a bicycle inner tube or something? What size tire, etc? Just checking before I reinvent the wheel.
