Very high quality tool vest!

I love that the weight is distributed, I can definitely wear my pouches for far longer than i could with regular suspenders. Over all a great and high quality product!

Hi Viz 701 Vest

I first bought the black 701 vest to replace my occidental tool belt. I wanted a modular system because of the work that I do. I’m a carpenter, and the work I do changes regularly, so it’s nice to unclip one accessory and clip on another. I bought the black vest knowing that the hi-viz was coming. I do volunteer work that requires five basic PPE, and one is hi-viz. having a hi-viz vest helps in that the vest wouldn’t cover my shirt and the hi-viz vest is rated higher then the shirts is wear. I carry A LOT of weight and barely notice it.

701 hi viz

I currently own the 701 and the atlas46 saratoga hands down the diamondback is more comfortable and easily adjustable with more options. The waist belt adjustment makes a big difference in weight distribution. I also have the shoulder pads and lumbar pads I would recommend them as they make the weight dissappear. If you're on the fence about this or the sratoga don't waste you're money and get the diamondback. I currently have atlas46 bags attached to the vest but soon I'll be getting diamondback instead. Shipping was super fast and custom service was above and beyond.

Very comfortable

Love the vest very comfortable and love how it distributes the weigh in your body and not your hips
