The Zero Gravity Kit is a fully-featured slackline kit for beginners. This thing has everything needed to get the first time slacker up and going on learning this new skill, including an overhead training line, arm trainer, tree pro with velcro keeper tabs, and a slack wrap for keeping things tidy. If you already know how to walk the line, this kit may not have the performance or length to keep you busy long, and the extra parts won't be necessary, but if you are new to the sport, and the price doesn't deter you, this kit could be just what you are looking for.

Our Analysis and Test Results
The Zero Gravity Kit is a basic slackline, that compares well with many of the other beginner options in our review. There are a couple of features this kit has that are worth mentioning and overall, for beginners, this is a great option.
Ease of Set-Up
Setting up the Zero Gravity is just as simple as any other ratchet based system. In addition to the slackline and ratchet, the kit also comes with a pair of 57" long tree protectors, an overhead training line, arm trainers and a slack wrap to tidy the excess webbing, keeping it out of the dirt. If you choose to use all the components for a beginner, the assembly process will take a few extra minutes, but overall, the set-up is simple and straightforward.
With an overhead training line and arm trainer, this line is pretty versatile. It makes an ideal learning rig, but will also be a decent, basic line for casual use for years to come.
With an overall length of 52', this slackline is somewhat limited by where it can be used. For most beginners, this should be plenty long, but after they get the hang of everything, they soon may be wishing they had a few extra feet or a slightly more dynamic type of webbing.
These days, slacklines in this category all tend to be quite comparable on the quality front. We haven't seen many slacklines over the past few years that we would consider poor quality. We didn't have any issues that made us take away major points, but the overall design is only decent when compared to similar models.
As with taking down any ratchet tensioned slackline, this does come with quite a bite. Always remember to keep hair and fingers clear when releasing it. When you set this line up, pay attention to assure you keep the webbing centered in the drum, because if the material drifts to the side-wall, it will rub hard against the edge when it's released and cause the line to prematurely wear out. We didn't have any problems but we did notice the drum tolerances were a bit loose, making this a possible issue.
This kit has a good set of extra features that will go a long way to helping a new slacker get the hang of things. The webbing itself has less bounce and stretch, making it slightly more stable, which is perfect for learning.
The overhead training line is decent but instead of using a smaller ratchet that most companies use, the Zero Gravity just uses a basic canoe strap style tensioner. This line also comes with a webbing arm-trainer that is then drooped over the training line that you hold onto, creating a more natural way of learning, allowing your arms to swing to catch balance instead of just grabbing for the line overhead when you start to fall.
While the tree protectors are pretty basic, they do have a decent 57" length to help get around semi-large trees. They also come with extra velcro tabs that can be used to hold the anchor webbing in place on the pads while you set up the rest of the system.
We were impressed by the better than average zippered carrying bag that this kit came with. It has a nice rubber handle grip and helps keep everything contained for traveling and storing the kit. This kit also has what they refer to as a "Slack Wrap". The Slack Wrap is nothing more than a piece of 2" wide elastic with velcro that is wrapped around the excess slackline webbing keeping it from dangling down into the dirt.
This kit has a fair value. If this system was priced lower it would attract more users that are looking to get into the sport, but at its current price, we feel there are better options. The system does have a pretty comprehensive list of features that are aimed at the first time walker, so if this is you, it's worth weighing the pros and cons that this line offers.
Any beginner looking for a starter kit will find this slackline to check all the boxes unless they are on a tight budget. While the price isn't outrageous, a similarly featured rig can be found at roughly half the price.
