The best Muay Thai heavy bag is a 6-foot banana bag, and the Fairtex HB6 is the reference model: long enough to take low kicks, middle kicks and knees on the same bag without moving your target. Outslayer and TKO also make long Thai-style bags in heavier fills for power strikers. This guide explains which size, weight and fill suit your body and your space, and how to hang a long bag without damaging a ceiling.

Why a banana bag is the Muay Thai standard
A standard boxing heavy bag is about 3.5 to 4 feet long, so a low kick to the thigh and a knee to the body force you to choose a single height. A banana bag is a long cylinder around 6 feet, so the same bag can represent the leg, the body and the head. In Thailand it is the bag you see in nearly every camp, hanging from a ceiling beam on chain. Because the bag is long, it is also narrower for its weight, which makes it a better target for round kicks.
Best overall: Fairtex HB6 banana bag
Fairtex is among the best-known Thai equipment makers, and the HB6 is its classic 6-foot banana bag. It ships unfilled, which gives you control of the density. Packed with shredded fabric it becomes firm and tough, suited to heavy kickers. A foam wrap over a core of fill gives a softer face that is easier on shins. Filled, expect a weight in the neighborhood of 90 to 100 lb. The trade-off is the work: filling a bag takes an afternoon, and the price does not include the hanging chain or swivel.
Best for power strikers: Outslayer 6 ft banana bag
Outslayer is a US brand with a reputation for sturdy bags and heavy fills, including 130 lb and larger sizes, and it offers a long warranty on its bags. Fabric-filled bags like this avoid the hard spots that sand fills develop over time. This is the bag for a larger striker who kicks hard and wants a bag that stays steady. The trade-off is weight: a heavy bag demands a strong ceiling mount and a good chain.
Best home value: TKO 6 ft Thai bag
TKO sells long Thai-style bags at lower prices than most specialist Thai brands. Around the 120 lb range, the bag is dense enough for solid kicks without needing a heavy-duty beam. It is a fair pick if you want the long shape without paying a premium. The trade-off is finish and long-term durability: stitching and covers on lower-priced bags can wear sooner under daily kicking.
Best for gym-style hanging: Everlast heavy Thai leather bag
Everlast offers a leather Thai-style bag for gyms and committed home users. Leather covers resist cuts from shin and elbow strikes better than basic synthetic covers. The trade-off is cost and break-in: a leather bag feels hard at first and takes time to soften, so it may punish shins before it settles.
Best for beginners: Venum Origins heavy bag kit
Venum’s Origins kit packages a bag with accessories, which helps a newcomer start without matching gear item by item. It is shorter than a full banana bag, so it works as a stepping stone for punching and basic kicks. The trade-off is that a shorter bag limits low kick practice and knee work, and you may outgrow it within a year.
How to choose a Muay Thai heavy bag
Pick the weight from your own body weight
A common guide is a bag that weighs about half your body weight, then adjusted for how hard you hit. A 160 lb person would start around 80 lb, and a 200 lb striker around 100 lb. For heavy kickers a bag at or above body weight stays steadier, but needs a stronger mount.
Choose the fill deliberately
- Fabric or textile scraps: even density, no hard spots, the usual choice for Thai bags.
- Foam layers over a core: softer feel, gentler on shins, good for beginners.
- Sand or grain: very dense, but it can settle into a hard base and create a stiff spot at the bottom.
Check the cover
Leather lasts longest but costs more. Vinyl and synthetic covers are cheaper and usually adequate for home use. Triple-stitched seams and reinforced straps matter more than the logo.
Match the bag to your ceiling
A 6-foot bag at 100 lb needs a mount into a joist or steel beam. A standard drywall ceiling will not hold it. Use a heavy-duty hanger rated for more than the bag’s weight, and add a swivel and a spring to absorb shock.
How much clearance a long bag needs
A 6-foot bag hung from a chain of about 1 foot needs roughly 7 to 8 feet of vertical room, and the bottom should sit around 6 to 12 inches off the floor. Allow at least 3 feet of clear space around the bag so that kicks and swings have room. Ceilings below 8 feet usually call for a shorter bag or a wall-mounted arm.
Care and what wears first
- The cover seams around the straps are the first to fail on hard-kicked bags.
- Fill compresses over time; punch or knead the bag to redistribute it if it feels dead in one spot.
- Wipe the cover with a damp cloth to remove sweat; salt breaks down leather and stitching.
- Check the chain, swivel and hanger monthly for wear.
Decision matrix: which bag for which kicker
| Your build and goal | Suggested bag | Filled weight | Fill |
|---|---|---|---|
| Light beginner, 130 to 150 lb, learning technique | 6 ft bag, soft fill | 60 to 80 lb | Foam wrap over core |
| Average adult, 160 to 190 lb, regular training | Fairtex HB6 or similar | 90 to 100 lb | Textile fill |
| Heavy kicker, 200 lb+, power work | Outslayer or TKO heavy Thai bag | 120 to 150 lb | Dense fabric fill |
| Limited ceiling height under 8 ft | Shorter heavy bag or angled bag | 60 to 80 lb | Any |
Shin conditioning and safety
Thai bags are firmer than boxing bags, and shins take time to adapt. Start with light kicks at 50 percent power for the first weeks, add intensity gradually and rest if you feel sharp pain. Use shin guards on new or hard bags. This article is general information, not medical advice; see a qualified coach or a health professional if pain persists.
Filling an unfilled bag: step by step
- Hang the empty shell first, or lay it flat so you can reach the opening.
- Pack the core with tightly rolled textile scraps or old clothing, in layers of about 6 inches, pressing each layer down.
- Wrap a layer of foam or a rolled mat around the center if you want a softer face.
- Fill to the top, close the cover and lace or zip it, then hang and punch the bag to settle the fill.
- Top up after a week, because settling usually frees up a few inches at the top.
Pack firmly: a loosely filled bag swings wildly and feels dead, while a well-packed bag holds its shape for years.
Frequently Asked Questions
How heavy should a Muay Thai bag be?
Aim for around half your body weight as a starting point, and go heavier if you are a hard kicker. A 90 to 130 lb bag covers most adult trainees.
Is a banana bag better than a regular heavy bag?
For Muay Thai, yes. The extra length lets you work leg kicks, body kicks and knees without changing your distance or the bag height.
Should I buy a filled or unfilled bag?
Unfilled bags such as the Fairtex HB6 let you control density and are cheaper to ship, but require time and materials to fill. Filled bags are ready to hang but often cost more.
Can I kick a heavy bag without shin guards?
Experienced practitioners condition their shins gradually, but beginners should start with a softer bag or wear shin guards. Increase impact slowly over several weeks.
How do I hang a heavy bag safely?
Attach it to a joist, beam or rated mount, use a chain and swivel rated above the bag weight, and inspect the hardware regularly. If you are unsure of the structure, ask a qualified contractor.
