I paired the Premier Body Armor Level IIIA insert with my Eberlestock Fade Sling, and the combination has quickly become one of my favorite EDC setups. The insert fits extremely well and adds meaningful protection without turning a lightweight, practical sling into something bulky or uncomfortable to carry.
That balance is what impressed me most. Protective equipment does very little good if it is so heavy or inconvenient that you eventually stop carrying it. With this setup, I don't feel like I'm carrying armor. I simply have the Fade Sling I already wanted to use, with an additional layer of protection built into it.
The insert feels well made, fits the pack as it should, and doesn't interfere with the organization or everyday usefulness of the bag. I've carried the two together and found the overall package comfortable, discreet, and extremely practical.
For me, this is exactly where personal protection equipment should be heading: lightweight, unobtrusive, and easy to integrate into things people actually carry every day. You hope you never need the protection it provides, but having it with you without significantly changing your normal routine is the entire point.
Premier Body Armor and Eberlestock make an excellent combination. If you already own a Fade Sling, this insert is one of the most worthwhile additions you can make to it. If you're building an EDC setup from scratch, I'd seriously consider the two together. Excellent fit, excellent protection, and most importantly, practical enough to actually carry.
