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.


The zipper stitching has started to fall apart. It appears that it is only single stitching, looks like I have to take it to someone who can double stitch the zipper as that would be a more economical solution than sending it back to the USA from Australia. Very comfortable but considering I use it at least 50hrs/week, not good enough after 3 months use.

Great vest

This vest is definitely one of a kind. It gives great support for the long days on the construction site and is very comfortable for all day wear. I definitely recommend this vest to anyone and everyone!

Life changer!

Just made the switch from a tool belt and the difference is insane! Will never wear a belt again! Usually carry quite a bit of tools and material and you can’t even feel the weight.
