EXTRA HEAVY 200 to 500 Pounds Muay Thai Bags and Heavy Bags
Made in USA!

400 lbs United States Navy Muay Thai Heavy Bags

Military Installations

We are honored that the US Navy Recruit Training Command - Great Lakes, IL called on KO Fightgear to supply 400 lbs heavy bags for its Boot Camp program. The Navy did extensive research on bag manufacturers before selecting KO Fightgear, noting that our bags are rated for the most aggressive training environments. To provide a sense of scale to the 400 lbs / 6 feet x 24 inch diameter heavy bags, our human gauge stands at 6 feet and weighs in at 185 lbs.

We offer custom label/logo silkscreen printing (as seen in the inset photo of the United States Navy Logo) click here for more information about custom labels/logos.

We've got great news to announce! KO Fightgear now has the logistics worked out to ship our extra heavy Muay Thai and boxing heavy bags that range in weight from 200 to 500 pounds throughout the lower 48 States and Canada. This is a big step up for us because in the past we only offered our extra heavy bags as a local customer pick-up.

For those of you that have trained on our bags, you know the performance and durability of our products. For those of you that have not, be sure to do your online homework. Read our Muay Thai Heavy Bags review and post on the combatives/mma and boxing forums to independently learn about our bags and our company, KO Fightgear. All our bags are 100% rag stuffed with no sand and no other fillers. Our filling technique is 100% performed by hand, inch by vertical inch that results in the "sweet spot" having a complete bag range from top to bottom, 360 degrees around. When our competitors advertise a rag filled bag, they're employing a hands-off mechanical method that with the flick of the switch, a piston is slammed into their bag for compression. Their method results in bulges along the length of the bag with a disappointingly inconsistent and limited "sweet spot". The components of our bags are "top shelf" industrial grade, engineered to perform at the truly elite professional level. Our bags are custom made, not mass produced, but most of all are by far the best in the USA and Made in the USA, right here in The Garden State of New Jersey. The construction of our 200, 300, 400, 500 and even 1,000 pound Muay Thai bags and heavy bags not only assures the performance of the bag's function, but also provides the structural support required for a very heavy hanging weight load. There is added work and materials that go into these bags compared to our 150 lbs and lighter bags. Every step in the manufacturing process as with all of our products is always done to go way over the top. The shell is two ply (two layers) heavy gauge non stretch vinyl for required support with multiple stitched seams providing well reinforced stress points. There's over 25 years of development and manufacturing experience that goes into each one of our bags.

These are the original tried and true Monster bags for a Vegas prizefight camp, a school that offers an additional training tool as a step up above the competition, and that special bag for home use.
