Size Guide


The Diamondback 701 Tool Belt Vest is the lightest, most durable, and adaptable on the market. Made with military-grade nylon mesh, the 701 keeps you cool and comfortable all day. Adjustable shoulder straps and a built-in waist belt replace your regular belt and suspenders, distributing weight evenly across your shoulders, waist, and torso. Attach any Diamondback pouch or accessory to the waist belt or torso attachment points to create a custom tool carrying system that perfectly suits your needs.

For added comfort and safety, the 701 features two bands of heavy-duty elastic at the back that absorb shock and allow easy access to safety harness connection points. The waist belt adjusts in the rear, eliminating a bulky buckle that could damage cabinets or other surfaces – ideal for carpenters and trim installers. Three adjustment straps under each arm ensure a comfortable fit for most users. When the workday's done, a hanging loop at the top lets you easily store your vest.

Bonus: Each 701 Vest comes equipped with twICEme technology. Upload your safety information to the twICEme app through your smartphone, allowing first responders to access critical details in an emergency. Suitable for individuals up to 6'5".

Best choice I have made

The vest is the best investment I have made in a tool belt in 20 years. I am an electrician and put full size bags and wear it for 8-10 hrs a day. my lower back don't hurt my hips don't hurt don't think just get the vest

Best of a lesser evil.

I’m a framer from Kentucky, and I carry a lot of tools usually. And I’ve bought everything from the big box store belts, Occidental’s, Badger’s, and I’ve always went back to diamondback. I do the 6” Belt with the Miter and the Eagle in the summer and the 701 vest with the Wrangell and the Elias in the winter and it’s probably the best at distributing weight and making you able to carry more but it’s definetly an “acquired taste” as you would say and took some getting used to. It’s pretty awesome if you’re corny like me and want to put some moral patches on it and load it down with attachments and accessories.

Probably the last work belt system I'll ever need to buy...

So different!! Sparky approved!

The 701 vest is a game changer! I’m an electrician and for my entire career I’ve been using traditional waisted tool belts/tool pouches. The 701 vest really frees up your hips and distributes the weight way better on your upper body. I’m looking forward to being more efficient with this setup, and looking to add more diamondback pieces for that ultimate tool setup for an electrician.

Way better than a traditional tool belt!

I’m a garage technician. I fix garages and install them. For years I would use a traditional tool belt but always felt there was something better so I started to do my research and came across the 701 vest and I’m glad I bought it! No more pants falling no more lower back pains. I can have it on all day and it doesn’t bother me at all! Mine is equipped with a mini nikko on the left and an impact holster and hammer holster on the right. I also have some clip punches on my mini nikko and two magnet pouches on my chest with some shoulder pads. It has made my job easier!! I highly recommend it.
