I need to buy a duty belt for work, I have no idea what to get. These are what Im looking at, any tips?

Nexbelt in my opinion is going to be a good belt for personal use, but I wouldn’t want it as a dirt belt per say.

This or safariland in same config,.

Depending what you're holding it might be better to do a 2 peice. Spending 20 minutes detaching and re attaching pouches everyday sounds like a pain. Check out blue alpha, most people recommend AWS

Big fan of the safelife belt. Incredibly rigid two piece belt system with a molle version available

I run this style belt. It’s great on my back. Pair it with the inner belt they offer and you’re set af.

I recently switched to the X Belt duty belt after a back injury. It's a game changer. Bit of a lead time but it was worth it. No more back pain.
