    This is my second chest rig I purchased from Gadsden Dynamics. High quality material used is the top priority for me. And these rigs are definitely high quality!

    Purchased the placard to integrate with a backpack. Quality is great and customer service was excellent.

    Got one for myself a few months ago. My son signed up for his first rifle class, so I gave him mine and got another for me. Easy to adjust for fit, simple, durable. And order shipped crazy quick.

    I came across this company 3days ago when they were recommended on the gun forums. I was searching for an AR Mag Chestrig that had a max of 4 mags and was low profile, Saw this Partisan rig, and it fit the bill perfectly. I went ahead and placed the order for it in brown, as well as their shotgun shell chest rig in black. The package just arrived an hour ago which is ridiculously fast. I tested both with pmags and shotgun shells and both rigs are amazing, I could not have wished for anything more. I have bookmarked their website as I will definitely buy more things from them in the future. Heck I may buy some more things from them tonight haha. Anyways, product quality is fantastic, shipping is fantastic and the company is professional and fantastic. I highly recommend this Partisan rig to anyone. A++

    Partisan chest rig

    Posted by Shane Gersley on Nov 8th 2021

    I work for a small contracting group teaching weapons and tactics. I needed a harness that I could wear all day while running walking and standing around. I have over a 50 inch chest and this harness fit perfectly with adjustment. It’s been through a couple classes in countless reload drills. It’s built durable, I expect it will last me a long time.

    Very Nice

    This is a very well thought out minimalist chest rig. It's super light and thin. The lack of MOLLE means I'm not tempted to add a bunch of heavy stuff to it -- It's just for ammo. I got the Multicam Black version. The webbing is very soft and pliable. It feels more like cotton than the super stiff and bulky webbing that you usually see on chest rigs. This makes it more comfortable when you're just wearing it over a t-shirt. The elastic mag pouches hold everything securely. 20 and 30 round PMAGs and 20 and 30 round Lancer mags all work fine. The back of the carrier is covered in hook material (in case you want to attach it to a loop-lined carrier). There's a rectangular section of loop material included to cover the hook backing if you want to use it just as a chest rig (and you don't want the hook material rubbing against your shirt). I will probably take a piece of 3D mesh material and sew it onto the loop so that the rig is a little more breathable. You wouldn't do that if you wanted everything to be as thin/light as possible. But I'm willing to add a 1/4" of thickness to get the airflow. Overall, it looks to be a great piece of equipment that should provide many years of useful service.
