This is just a quick blurb about something stupidly simple, but awesomely useful: Nite Ize Gear Ties. These gear tie thingies are glorified twisties; you know, those annoying wire ties that keep loaves of bread from escaping their bags. The Nite Ize product is more durable, rugged, strong, and colorful . . . but it's still basically a bendy wire. OK, it's a thick bendy wire wrapped in a pretty rubber sheath.
These gear ties come in various lengths ranging from 3 to 64 inches. I have a handful of the 3-inch size and a couple of the 6-inch size. I use them for my charging cords, speaker wires, LAN cables, and headphones. You'd be surprised at how useful they are. Really.
Not much more to say about these gear ties. The instructions are straightforward and very easy to understand: "bend it around something". You owe it to yourself to check these out. All the cool kids have them now.
