Best Heavy Bags for Muay Thai
A Muay Thai bag is chosen by length, not weight. A standard 42 in boxing bag stops at your hip, so a low kick lands on nothing. Six bags that reach the floor, ranked on length, diameter and what stops the bottom third turning into concrete — and the ceiling measurement to take before you order.

Scores are our editorial judgment from published specs and manuals, weighted for a first home setup — not lab measurements. We have not tested these units.
Length, not weight, is the spec that matters
Most heavy bags are about 40 to 42 in long. Hung at a sensible height, the bottom of a bag like that sits around your waist. That is fine for boxing, where every strike lands between the chest and the head. It is useless for Muay Thai, where the low kick to the thigh is the most-used weapon in the sport — there is simply nothing there to kick.
A Muay Thai bag, often called a banana bag, is 5 to 6 ft long so the striking surface runs from head height down past the knee. That is the entire reason the category exists. Weight follows from length: a 6 ft bag packed properly ends up somewhere between 100 and 150 lb, which is why the weights look heavy compared with a boxing bag. The weight is a consequence, not the target.
| Pick | Length | Diameter / girth | Fill |
|---|---|---|---|
| Outslayer #01 Muay Thai | 6 ft | Approx. 14 in | Compressed fabric only, no sand |
| Century 100 lb Muay Thai | 72 in (88.5 in with straps) | 42.5 in circumference | Impact fiber |
| Century Creed Muay Thai 100 lb | Not published | Not published | Foam liner over a sandbag core |
| TITLE Synthetic Heavy Bag 90 lb | 60 in | 13 in | Not published |
| Outslayer 100 lb | Standard boxing length | Not published | Compressed fabric only |
| Aqua Training Bag 75 lb | Teardrop, not full length | 15 in | Water |
The three specs that separate a good Muay Thai bag from a bad one
- Fill that does not settle. This is the difference nobody mentions until their bag is a year old. Fiber-and-sand fills compact under their own weight, and the bottom third — exactly where your shins land — turns hard. Two fixes exist: fabric-only fill (Outslayer state they use compressed fabric and no sand) or a foam liner over the core (Century's Creed line). Both are on this list at the top.
- Diameter or girth. Knees and body kicks want a wide target. Century publish a 42.5 in circumference, which is about 13.5 in across — generous. A 13 in bag is a boxer's diameter and feels thin under a round kick.
- Straps rather than chains. Chains are loud, they twist, and on a long bag the twist is worse because there is more bag to wind up. Both Outslayer and Century use web straps.
How this list is ordered
By our published heavy bag rubric — weight fit, setup and space demand, strike surface, stability and value — read for Muay Thai rather than boxing, which means length and anti-settling fill carry the argument. We have not tested any of these bags, we own no test units, and there is no lab behind the scores. Every spec comes from the manufacturer page cited under each card, checked on 26 September 2026.
What if your ceiling will not take a long bag?
Two honest options, both on this list. The TITLE 90 lb at 60 in is the shortest bag here that is still long enough for a low kick, and 60 in plus hardware fits a standard 8 ft room. Or go to a water bag: the Aqua at 15 in across is wide and forgiving on shins, and although it is a teardrop rather than a full-length bag, it hangs shorter and takes a round kick to the body well. Neither is a real substitute for a 6 ft banana bag. Both are better than a 6 ft bag you cannot hang.
A freestanding bag is the third option, and the weakest one for Muay Thai — the base is in the way of exactly the low kick you are trying to throw. The freestanding vs hanging comparison covers the trade-offs.
Mounting a 130 lb bag
A filled 6 ft bag is two to three times the load of a beginner boxing bag, and it swings with more momentum because there is more of it. That rules out most light stands and any ceiling fixing you are unsure about. Into a joist or a structural beam with a rated mount, or onto a stand rated well above the bag's filled weight — the mounts roundup and stand vs ceiling mount have the numbers. Tie the bottom D-ring down if the bag has one; a long bag swings further than you expect in a garage.

Pick 01 · Heavy bags · REF HEA-01
Outslayer #01 Muay Thai Punching Bag (6 ft)
Outslayer
The banana bag to buy once: 6 ft of striking surface, fabric-only fill so the bottom third never turns to concrete, and a 10-year warranty.
Best for
Low kicks, knees and long combinations in a garage with the height for a 6 ft bag
Why it is #1. Six feet of surface, approximately 14 in across, heavy-duty vinyl, a 10-year warranty, and — the part that matters most — Outslayer state they use compressed fabric only, with no sand. That is the published answer to the concrete-bottom problem every long bag develops. It also comes unfilled, soft-filled or filled, with soft-filled running roughly 20 to 30 lb lighter. You need the ceiling height for it.
Pros
- 6 ft of surface means low kicks land on bag, not on the floor below it
- Outslayer states compressed fabric only, no sand — the usual cause of a rock-hard bottom third
- Heavy-duty straps in the same material as the shell, so no chain noise
- 10-year warranty published on the product page
- Sold unfilled, soft-filled or filled — soft-filled runs roughly 20–30 lb lighter
Cons
- Needs real ceiling height: 6 ft of bag plus straps and a swivel wants a tall garage or basement
- Filling it yourself is an afternoon of work if you buy it unfilled
- A 130–150 lb bag needs a joist or beam mount, not a light stand

Pick 02 · Heavy bags · REF HEA-02
Century 100 lb Muay Thai Heavy Bag
Century
The one long bag with every dimension published: 72 in of body, 42.5 in circumference, vinyl over impact fiber, chains and web straps in the box.
Best for
A first Muay Thai bag when you want the numbers before you drill anything
The one with every number published. 72 in of body, 88.5 in including straps, 42.5 in circumference. That last figure is the widest target here, which makes a real difference to knees and body kicks. Vinyl over impact fiber with chains on web straps. Fiber does settle over time, and Century charge a flat oversize return-shipping fee, so get the measurements right first.
Pros
- Century publishes the full length with straps (88.5 in) — the number you actually need to plan a mount
- 42.5 in circumference gives a wide target for knees and body kicks
- Ships with heavy-duty chains attached to web straps
- More than two feet longer than Century's standard vinyl bag
Cons
- Fiber fill settles; expect to punch the bottom third loose periodically
- Century charges a flat oversize return-shipping fee — check the fit before you order

Pick 03 · Heavy bags · REF HEA-03
Century Creed 100 lb Foam Lined Muay Thai Heavy Bag
Century (Creed)
A foam layer over a sandbag core — the construction that keeps a long bag evenly firm top to bottom instead of settling into a brick.
Best for
Someone who kicks hard and does not want to re-pack a bag in a year
The anti-settling build. A reinforced performance foam layer over a sandbag core, which is the construction that keeps a long bag evenly firm instead of compacting into a brick at the bottom. Lace-closure top so you can open it and top up the fill. About double the price of the plain vinyl Muay Thai bag, and Century publish no length or diameter for it — the two reasons it is third rather than first.
Pros
- Century states a secondary reinforced foam layer over the sandbag core — the fix for a hard-bottomed bag
- Lace-closure top means you can open it and top up the fill
- Reinforced nylon straps attached with leather tabs and reinforced stitching
Cons
- Costs roughly double the plain vinyl Muay Thai bag
- Century publishes no length or diameter for this model
- Oversize return shipping is charged at a flat fee on Century's own terms

Pick 04 · Heavy bags · REF HEA-04
TITLE Boxing Synthetic Heavy Bag (70 / 90 lb)
TITLE Boxing
The cheapest bag on this site with published dimensions and a water-resistant Cordura lining — and the 90 lb runs 60 in, long enough for kicks.
Best for
A garage bag on a budget where damp is a real risk
The bag for a standard 8 ft ceiling. The 90 lb runs 60 × 13 × 13 in — the shortest bag here that is still long enough to throw a low kick, and short enough to hang properly in an ordinary room. Synthetic leather over a water-resistant Cordura lining, which matters in an unheated garage. 13 in across is narrow for kicks, and no hanging hardware is named in the listing.
Pros
- TITLE publishes exact dimensions for both weights — rare at this price
- Inner-woven Cordura lining that TITLE calls water resistant, which matters in an unheated garage
- The 90 lb at 60 in is genuinely long enough to work low kicks
Cons
- 13 in diameter is narrow — a body kick lands on a smaller target than a Muay Thai bag
- No hanging hardware named in the listing; budget for a swivel and straps

Pick 05 · Heavy bags · REF HEA-05
Outslayer 100 lb Heavy Bag
Outslayer
US-made, 55 in tall, straps sewn on so there's no chain to rattle, and a 10-year warranty — the buy-once bag.
Best for
The one bag you never replace, if the budget allows
Outslayer build quality at boxing length. The same fabric-only fill philosophy and made-in-USA construction as the 6 ft bag, in a standard-length bag. On this page it is the compromise pick: buy it if you box mostly and kick occasionally, and you want a bag that will not go hard at the bottom. It will not give you a low kick.
Pros
- Made in the USA with a 10-year warranty
- Sewn-on straps: no chain noise, and nothing to unhook
- Ships filled (in a reusable vinyl cover) or unfilled; soft-fill option weighs 15–20 lb less
Cons
- 55 in tall — measure your ceiling and mount height first
- Costs two to three times an Everlast Elite

Pick 06 · Heavy bags · REF HEA-06
Aqua Training Bag 15 in / 75 lb
Aqua Training Bag
A teardrop bag you fill from a garden hose to 75 lb — ships at 9 lb, has no hard spots, and drains for a move.
Best for
Apartments and anyone who moves — or whose knuckles hate a hard bag
The kindest surface for shins. Water gives under a kick in a way packed fiber does not, and at 15 in across it is a wide target for body kicks and knees. It is a teardrop, not a full-length bag, so there is no low kick — and it ships light and fills at home, which solves the freight problem. On this list as the low-ceiling and sore-shins answer.
Pros
- Water fill means no settling and no hard bottom third
- Ships light and drains in minutes — the only heavy bag that fits a walk-up apartment
- Made in New York; 1-year warranty
Cons
- Teardrop shape is shorter than a straight bag — low kicks and some body-shot angles feel different
- A puncture is a wet floor; keep it away from anything sharp

Buying guide
Filled, unfilled or soft-filled?
A filled 6 ft bag is a freight shipment. Buying unfilled saves a lot on shipping and costs you an afternoon: you pack it yourself, in layers, compressing as you go, and the quality of your packing decides how the bag feels for the next decade. Soft-filled is the middle option — Outslayer offer it and it runs 20 to 30 lb lighter, which also makes the bag kinder to shins and easier to mount.
If you pack it yourself: use fabric, not sand. Sand migrates to the bottom and sets. Old clothing, cut into strips and packed hard, is what the fabric-only bags use.
What else you need before you kick a bag
- Shin guards. Not optional on a hard bag. Your shins adapt slowly and bruised periosteum takes weeks.
- Gloves with a shorter cuff. Muay Thai gloves let you check kicks and clinch — see boxing vs Muay Thai gloves.
- A mount rated well above the filled weight. 130 lb swinging is not 130 lb hanging.
- Ankle wraps or supports if you kick barefoot, which most people do.
Mistakes to avoid
- Buying by weight and ignoring length. A 100 lb boxing bag is still a boxing bag.
- Ordering a 6 ft bag for an 8 ft room. Measure the drop from your fixing point first.
- Packing it with sand. The bottom third will be solid within a year.
- Kicking a hard-bottomed bag without shin guards, then wondering why your shins hurt for a month.
- Hanging a 130 lb bag from a fixing rated for 70 lb.
FAQ
Frequently asked questions
What size heavy bag is best for Muay Thai?
Length is the spec: 5 to 6 ft, so the striking surface runs from head height down past the knee for low kicks. That usually lands somewhere between 100 and 150 lb filled, but the weight is a consequence of the length, not the thing you should be shopping for.
Can you do Muay Thai on a normal boxing heavy bag?
You can do everything above the waist. You cannot throw a low kick, which is the most-used strike in the sport — a 42 in bag ends around your hip. If you only have a boxing bag, work punches, knees and body kicks on it and drill low kicks on pads.
How much ceiling height do you need for a 6 ft Muay Thai bag?
Roughly 8 ft 6 in to 9 ft clear, once you add straps, a swivel and a mount above the bag and leave the bottom off the floor. In a standard 8 ft room, choose a 5 ft bag instead — a shorter bag hung properly beats a long one dragging.
Why does the bottom of my heavy bag feel hard?
The fill has settled. Fiber-and-sand mixes compact under their own weight and the densest part ends up at the bottom, which is exactly where your shins land. The published fixes are fabric-only fill or a foam liner over the core — both are on this list.
Are freestanding bags any good for Muay Thai?
The weakest option. The base occupies the space where a low kick would land, and the bag rocks rather than swings. Better than nothing if you cannot hang anything — see freestanding vs hanging.
Should I buy the bag filled or unfilled?
Unfilled saves a lot on freight and costs you an afternoon of packing. Fill it with compressed fabric in hard layers, not sand. Soft-filled is a good middle option and is kinder to shins.
Do I need shin guards for bag work?
Yes, for anything beyond light technique work. A packed bag is unforgiving on the shin, and the adaptation takes months. Shin guards for a first year are the cheap end of avoiding a long layoff.
