If you’ve kept up with any part of the outdoor news in the last couple of years, then you’ve likely noticed that previously fringe outdoor sports are on the upward swing in popular culture. With the mainstream rise of documentaries like Alex Honnold’s “Free Solo” and cult-classic films like “Valley Uprising,” the outdoor world has experienced somewhat of a Renaissance, and with it has come a slew of new and interested enthusiasts.

Unfortunately, too often the outdoor world can be a place where the lingo, the gear and the wealth of experience of the pros have served as an obstacle to those looking to learn and engage on a beginner’s level. In the world of outdoor sports, things like climbing, backpacking, and kayaking can feel like exclusive clubs reserved for those who already know and understand the language. But the reality is, those are all just different outdoor activities, open to anyone who is willing to give them a shot.

Here at The Dyrt, we’re working to open the outdoor world to everyone, one campground review at a time. To help with that, we’ve created this quick overview of one of the most important tools in the outdoor world: the carabiner.

Although commonly found in everyday life, the carabiner’s true functionality is on full display during a variety of outdoor sports.

If you’ve never had the chance to use one, things can get pretty confusing. Is it for climbing? For hanging on? For attaching things? For holding your water bottle? The answer is yes, but it’s a bit more complicated than that.

Generally speaking, the carabiner is a coupling link with a safety closure, meaning it’s basically a tool that’s designed to keep you safe, consisting of a curved body with a straight or curved bar known as the gate that opens and closes.

The locking or closure mechanism on every carabiner is meant to allow for things to be attached to it without the fear of them coming off. Unlike a traditional coupling link, which has no closure point, carabiners offer easy clipping ability and a secure waypoint for whoever might need one.

That said, there are a few different kinds of carabiners, each of which has a slightly different use.
