After going through a cheaper bag (all the sand and filling settled on the bottom making it dangerously solid) I went on the hunt for something else. I'm about 270, and I needed a big bag that could stand up to both punches and kicks. This seemed to fit the bill, but I never worked out on a water bag. I gambled and got this through Amazon (via Sportsmans guide). It's a VERY simple design, and I honestly can't see how it would ever break down. The "core" is a big heavy gauge plastic cylinder with a screw top; it's about the size of a small scuba tank. There is one layer of very dense uniform foam around this, and that's it. The cover is a little slick, but it too looks bombproof. Word to the wise: IF YOU GET A BAG LIKE THIS, DON'T FILL THE CORE TO THE VERY TIPPY TOP, WHEN YOU STRIKE THE BAG THE CORE COMPRESSES AND THE WATER HAS NO PLACE TO GO AND YOU COULD CONCEIVABLY CAUSE A RUPTURE. You only have to leave three inches or so to guarantee no problem. As far as working out on it, I like it. It is a little different from a traditional bag. Whereas a traditional bag feels more like "dead" weight, this bag has quite a bit of "life" to it. Again, not necessarily a bad thing, but different. The best part of this bag is knowing that each impact is a little less jarring and virtually any spot you hit the bag (with the exception of the very top and very bottom) has uniform resistance. All in all, I expect this to be the last heavy bag I'll ever need to own, there will always be others in the gym though ;-) {{this review is for the 120lb XL, but the 80?lb L is identical in design}}

I've been using traditional heavy bags for years, and ran into the same problem: the filling ultimately settles, and you end up with what feels like a petrified tree.
The Hydrocore, on the other hand, has a heavy gauge plastic core that you fill with water to give it the variable amount of weight you want, surrounded by a thick high-density foam, which never settles, solidifies, or becomes an issue. So, the feel, and response of the bag is consistent over years (I've been using it approximately three years). Additionally, since the outer core is foam, it has give, and (in my humble opinion) a more lifelike feel and reaction.
Another plus is that it's a double ended bag, so you can tie it down from the bottom, and restrict it's movement, which I've always appreciated when delivering combos, and kicks.
I've had it for over three years, and I've clocked quite a few hours/week on it regularly, and it has yet to show any heavy wear or abuse. So, it gets a thumbs up for durability.
I give it five stars, since I couldn't find an appreciable downside on this bag.

I am a six foot 210 pound fourth degree black belt and have been using a water core bag for over twenty years. I have heavy kicks and punches and even use it for stick training. I lost the cap during a move, and being tired of improvising, finally broke down and ordered this bag. I had the same problem as the above reviews with traditional bags in the past, and loved my water core bag; however, my old bag had a plastic/rubber style bladder core which allowed a nice body feel and give to it. This bag has a POLYETHYLENE or hard plastic core. This is probably so that there's less chance of rupture, but the buyer should be warned this has yet a different feel to it. It still feels better than the traditional bag, and I do enjoy using it but if you're expecting the old bladder type core be warned this is a different bag with a different feel to it. Still a good bag though.

My wife showed me this bag after hearing me complain about my other heavy bag that consolidated to where it felt like hitting a tree trunk. I made my decision to try it based on the reviews I read, and I wanted to add my own review. This bag has the following attributes:

- Uniform hardness, and it cannot consolidate anywhere because of the foam layer. I can hit the top or the bottom with the same degree of resistance.
- Soft enough to where I can practice without gloves, and can even practice front kicks and open-hand strikes
- The water absorbs much of the impact, making it a quieter bag to hit (it does not rattle the whole garage like the other bag)
- Sturdy construction. It has a durable outer shell that is soft enough to where it won't scrape bare knuckles. The inner tank is heavy gauge plastic that can absorb impact without breaking.

Hitting this bag feels a bit weird at first if you are used to a sandbag-weighted system, but you soon become used to this bag, and it really does have a life-life feel upon impact. I repeat advice from another reviewer: do not fill with water to the tip top. Allow 3" space from the cap to prevent water spillage.

Excellent bag for the money.

Firstly, as with other reviews, this is a very different feeling compared to most common stuffed bags. It's hard to really describe how different it is in words, but the impact and the sound both are different (not bad, just different than most people are used to).
When you hit this you can feel the internal water reverberate, taking some of the impact. Initially, it's a very strange feeling to get used to, but after a workout, you notice how much less impact you've taken.

- I like the impact absorption, especially with kicks. Compared to my old bag that became hard on the bottom, this is easy to kick and you barely even notice the impact when kicking with all you've got. I presume that when the outside foam on this bag wears out, it won't feel great though, but new foam will be easy enough to put in.
- This is somewhat of a con, but I feel it leans more toward a pro. When you get this, you'll pick it up and wonder if anything is in the box. This makes it a great pro for transport. Get it setup wherever you want it, then fill it up (hopefully you can get a hose to it). The con side of this is if you move or need to move the bag, now that it's filled with water, it's awkwardly heavy and you need a good method to drain off the water (I recommend a hose to drain if you have a drain that is lower than the bag). If it's setup somewhere that is not close to a place to drain, then the pro of this being light goes out the window until you can get it drained.

- I would have rather not had the chains be a single connected unit and used S-hooks or something else. The chains were a little long for my situation, and it would have been nice to simply connect an S-hook higher on the links to raise it up a little.
