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.

Perfect! No more back pain!

Amazing performance! I can wear it all day!

Comfortable and unique. High quality and durable.

The only problem with this vest is the amount of times I get stopped and asked where I got it from, every single day. People love it.
It’s different than any other vest out there.
I love it.
