First off let me start by saying I have not ever written a customer review on here. With that said, when you absolutely love a product, it's nice to give thanks to its maker and supplier. I have trained on several types of heavy bags from different companies (some very well known world wide) over the years. As a new school owner though, I wanted to make sure the quality of equipment we were going to be putting in our school was top notch. Several months ago, while pricing heavy bags from different suppliers, I came across Outslayer. I was intrigued by what I saw and read about the products. After reading a lot of the customer reviews, I decided to give them a shot so I ordered the 100 Lb MMA bag to test. Wanted to start with a standard bag to test the quality before getting into the larger bags. That bag arrived quickly and must say I loved the covering case it arrived in. Made sure the bag was protected during its cross country journey. Plus the covering case makes it nice to pack the bag up during moves if you move or need to transport the equipment to a different training location. Once the bag arrived, I immediately took down one of our other existing bags and replaced it with the Outslayer bag. The appearance alone of the bag handing there gave a very nice professional look but yet has that look that says "let's train" ! So that's what we did. Over the past several months, we have given that bag all we could from basic striking to hard core heavy bag workouts. During these workouts we have utilized our full array of Muay Thai strikes including knees, and elbows. No injuries, no cuts, no burns from the material the bag is made from ! The bag gives just the right amount that allows even the beginner striker to use without injury but yet allows the hardest of hitters to bang until they flat out can't go anymore. The filling is done perfectly, not using sand but using fabric which gives a realistic feeling when striking. This bag has been put to the test and then some by every member of our training crew and has been the best equipment investment I have ever made. There has been no settling with the filling, unlike the majority of all the other bags I have trained on. It is still in the same shape and form that it was on day one ! With such success of the initial bag, I knew I had found my supplier for all the bags in our school. So I then went ahead and purchased the 130 lb 6ft Muay Thai Bag. Again, delivery was fast, same great covering and transport case. It was hung first day it arrived and we went to work. This is an incredible bag. The height is perfect and allows for changing levels of striking, from working low leg kicks to high head kicks and works great for students of all sizes. Same great quality Again just like the first bag, the filling is incredible. Very even all the way through with just the right amount of give to create as much as a realistic striking experience as a heavy bag can. The cost for these bags are great. No complaints at all about that. I must admit that I am surprised that these bags do not cost more because the quality of the bag is top notch so with that, you are really getting the best deal for your money. with the opportunity to pick your colors and customize your bags also, Outslayer is a great company to order from. If you have actually taken the time to read this, then let me finish by simply stating this.....if your are looking for a great bag that will hold up and allow you to get the most out of your training, then stop searching and just go ahead and add this bag to your cart and make the purchase. Truly the best bag I have ever trained on !! We will from here on out only use Outslayer heavy bags in our training facility and are in the process of ordering more. Job well done Outslayer !
