K9R - M4 Tactical MOLLE Vest
K9R - M4 Tactical MOLLE Harness (Vest)
MADE IN THE USA - LIFETIME WARRANTY
The M4 Tactical MOLLE Harness (Vest) is built to be the best-fitting harness for standard and larger small-to-medium breeds. It's lightweight, durable, and made with premium materials — built tough for hard, rough use, with airflow that keeps your dog comfortable through walks, adventures, and even working shifts. It's a rugged harness hand-built in-house in our own shop, delivering a tailored, secure fit rather than a generic one-size-fits-most feel.
Laser-cut from premium Cordura nylon, the M4 uses precision manufacturing to create a contoured, ergonomic shape most harnesses can't match. A five-point adjustment system lets you dial in a comfortable, custom fit. Four quick side-release buckles get your dog geared up fast. Lightweight padding on the main body keeps things comfortable even when the MOLLE panels are loaded up with gear. A heavy-duty top-center grab handle gives you added control and support whenever you need it.
The chest area is kept minimal — just webbing, no padding — for maximum airflow right where dogs need cooling most. Two leash attachment points give you multiple ways to safely control your dog. Loop panels on both sides hold ID and morale patches, with MOLLE slots in between for accessories and gear.

Great craftsmanship and materials
Impressed with how well it is put together!
Very happy with this purchase. I've been looking and shopping around for a while looking for a harness that would fit my bub perfectly. This one fits Thor like a glove! 🙌🏻
Ordered this harness from a recommendation and I'm very glad I did! I hike a lot with my corgi and it is hard to find something that fits her unique shape while also being sturdy. This harness hits both marks. I am very happy with it!
I love the look and I love picking just the right morale patch to customize the harness. My dog is a terrier mix and has some real swagger so the multicam vest is adorable
The harness is durable material that I can tell will last for a long time. I’ve had trouble with the buckles falling with other harnesses, and these seem to have a better built. I like that there are many accessories that I can put on the harnessed. It’s an overall great item and I recommended to.
Solid product. Quality looks great and the fit is spot on.
Good quality harness and easy to use. Love it.
Amazing. My little Boston loves it. Great quality.
These vests are sturdy and fit great on french bulldog bodies.
Its a perfect fit for my dachshund and it looks good too! My corgi is next!
Cant recomend this enough. Adopted another blue heeler, and had this on order same day since we loved the first one so much. Well thought out, and well made.
These harnesses are awesome. This is our 3rd one from them. This one is for our new puppy. Quality is great and everyone always loves them. Especially the patches we can add. Our little guy is going to look badass.
Great product great company
Great construction and fit for our standard dachshund!
I got this to be a service dog vest and I was also looking for a sturdy well built for a way to safely secure Jake into my car. I wanted to make sure that it would hold up to sudden stops and the stitching was strong enough that the D-rings would hold up. I personally spoke with the owner of this company about its strengths before buying. I could not be happier because I received personal attention with a real human, the quality of the product, and also how a size for my 10 month old Australian Cobberdog. He ways 24 pounds and the size is excellent for him. It doesn’t dig, and on top of this the fact that this product is made in the USA. I will happily recommend to others!
These lil tactical vests are awesome for these little four-legged wanna-be warriors! I've boughten numerous K9R-M4 Tactical MOLLE Vests and have been happy with them.
