@fundamentalfightingWhat Customers Say
What a beautifully elegant punching bag you designed! I have just received it and it's gorgeous. It fit perfectly into my library and finally allows me to train at home.
the python bag is sick, and it's one less thing I have to leave the house for. As a pro fighter every bit of training efficiency counts, thank you!
We've had the snakeskin bag up our MMA gym for a few months now and it's getting a lot of use from members and we've gotten positive feedback on it. There's nothing else quite like it!
amazing feedback and aesthetic appeal
I've been loving my Python bag! Its form factor and weight make it possible for me to train in my home office, which would've been difficult with other heavy bags on the market. It's not so small/light that it's useless as a heavy bag, and it's not so big/heavy that it's a permanent fixture in my workout area. It hits the perfect sweet spot where I can train hard while also being able to hang/unhang it at will. Also, Zack went above and beyond to make sure that my space could accommodate the bag before I purchased it. Top notch customer service!
We're using the bag in my gym so much — it's amazing. Wishing you the best.
I've used many heavy bags, but this one (the red one) is for sure the one I'll use daily for my training. The slim design really simulates a torso. It's my new favorite punching bag.
Don't get me wrong the custom designs are sick but I just wanted something simple that fits my apartment without standing out. Filled mine about 60/40 shredded fabric to rubber mulch and it hits solid. The bungee anchor cord on the bottom is clutch for dialing in swing and rebound. Price point made it easy to pull the trigger.
I've been wanting to learn Muay Thai for years but never had space for a traditional heavy bag. This bag changed everything - it fits perfectly in my small home gym, the quality is way better than I expected. I look forward to my workouts now. I'm building real skill instead of just doing cardio. Worth every penny.
I'm a dad trying to stay in shape at home. This bag makes me excited to train. My kids think it's cool, my wife likes how it looks, and I'm actually consistent with my workouts for the first time in years.
This bag fits my goals for the new year. The color blocking is bold but not gaudy, and the compact size means it doesn't dominate the room. Quality feels premium.
I've been personal training for six years and getting clients excited about bag work used to be a struggle. Now they request it. The strike zones gives them something to focus on, and the compact size means I can even bring it to in-home sessions. Quality is excellent and it's handling multiple clients daily without any wear issues.
Pre-ordered this and the wait was totally worth it. I LOVE training on this thing. Only giving 4 stars because I wish there were more design options to choose from.
15 years of Muay Thai has taught me what quality equipment feels like. This bag is professional-grade... I went with 100% rubber mulch fill and it feels actually hitting someone. The python design isn't just aesthetic, it actually helps me work on precision combinations even at my level.
My home gym is basically a corner of my garage, but this bag delivers hardcore training without the bulk of my old gear. Best piece of equipment I've purchased for home use.
This bag is genuinely beautiful and functional, just the right size for my apartment, just the right weight for real training.
Teaching taekwondo to kids and teens, engagement is everything. The color zones have transformed how I teach combos like "red-yellow-black" is so much more effective than "low-high-mid." Students are having more fun AND training harder.
This is a really well-made bag with an awesome design. I'm giving it 4 stars only because it took a little getting used to... I've never hit anything quite like this before. Once I dialed in the fill the way I wanted, it's been perfect for both gloved and bare-knuckle work. The craftsmanship is top-notch and the pattern genuinely helps with accuracy.
The bag is fantastic - design, quality, durability all exceed expectations. I'm giving 4 stars only because I'd love to see a 100-130lb version for those who want more resistance. For technique and combination training, it's absolutely perfect. Already recommended it to my entire gym.
I coach both BJJ and striking, so I need equipment that works for different training styles. This bag is compact enough to move around, tough enough to handle daily abuse whether on the ground or hung up. The 4 stars is only because I'd love an even heavier option too.
In 30 years of teaching karate, I've seen every kind of training equipment, ancient to modern. This bag honors the traditional martial arts emphasis on precision while incorporating contemporary understanding of biomechanics. My students are seriously excited, and now we've got them at home and in the dojo.
We run a small MMA gym and wanted equipment that looks as good as it performs. This bag does both. Members actually use it instead of just walking by. Holding up great under heavy use too.
Bought this for my MMA gym as a premium option and it paid for itself immediately. Three people signed up specifically mentioning this bag during tours! I use it myself and love that it's both accessible for beginners and has lessons to teach pros too.
Been fighting professionally for 8 years and this bag has improved my striking accuracy, movement, and fight IQ. My coach noticed the difference in my combinations within two weeks.
Been using this daily for several weeks now and it's holding up great. No loose stitching, fill hasn't shifted, still looks brand new. Already told everyone at my gym about it.
Coaching university-level kickboxing, I need equipment that pushes athletes to improve. The color blocking has elevated our technical training and athletes compete to hit specific color sequences. This bag takes the place of several other tools in our gym.
The slim profile + color sections create such clear visual targets that my striking has become more deliberate and precise. I'm not just hitting the bag anymore, I'm placing every punch and kick exactly where I want it. Game-changer for technique refinement.
Living in a small apartment, I thought I'd never have room for a proper heavy bag. This compact design fits perfectly in the corner of my room and the quality is incredible. Finally get my daily workouts in without driving to the gym!
I've trained champions and seen every innovation in boxing equipment. This bag represents a genuine advancement. The color targeting isn't gimmicky, it's functional brilliance that helps fighters develop better habits faster. Wish this existed when I was competing.
Installed this in our CrossFit box three months ago and it's been the star of every class. The unique design gets people excited about bag work who usually skip it. Plus the construction quality means it's holding up great despite constant use from 60+ members.
Added this to our Kyokushin dojo a few weeks ago. The students use it for striking practice and conditioning. Build quality is solid and the design actually helps them focus on specific target areas. Good investment for a smaller training space.
I teach at a small kung fu school and we needed a bag that could handle daily use without taking up too much space. This one fits in our modest training area and the students are shocked at how alive this thing is. It moves just enough to make them move and is slim enough to make them focus.
What people are saying
Straight from martial arts Reddit communities
The 8 inch target mimics torso width and forces cleaner striking than a 16 inch cylinder... genius engineering on the sectional liner system.
My gym removed its bags and I have no way to drill combos outside of class — this post just solved an issue I've been having.
The bag looks great and isn't breaking the bank.
I've seen this in Jeff Chan's videos. He always talked good about it too.
This solves the exact problem that I have. Bracing my garage for one.
It's designed with fighters in mind, which is surprisingly rare outside of the usual brands.
The color blocks are a great way to visualise the different targets.
Think the "zones" with colors are a fantastic idea.
I like the different color zones. It gives you areas to target.
The world needs more good options for low space training.
Very nice, I like that it's lighter than a standard bag.
Sounds pretty space conscious. Not a bad idea.
Being able to customize the fill in each liner section — that is killer.
Impressively well thought through, and impressively executed.
I like when people make stuff like this to solve a problem.
Got a sample of this — taking it in to my coaches at Churchstreet.
Why the Bag Exists
Most heavy bags are built for commercial gyms — 13–14" wide, 100–150 lb pre-filled, needing 8+ ft of ceiling and freight delivery. If you train at home in an apartment, garage, or basement, they don't fit.
The Python Bag is 8" wide, 55" long, with short straps for 7 ft ceilings and adjustable fill from 30 to 65 lb. It ships unfilled by standard carrier and you fill it at home to your weight.
Every design is community-voted through The Lab and pre-order funded. Direct-to-consumer, no retail markup.
Frequently Asked Questions
What are the Python Bag's dimensions and weight?
The body is 55" long and 8" in diameter. Fill weight is adjustable from 30 to 65 lb — you choose the weight when you fill it at home.
Does it ship filled or unfilled?
Unfilled, by standard carrier. No freight, no liftgate. You fill it at home with shredded fabric, sand bags, or rubber mulch to the weight you want.
Can it hang in an apartment or low-ceiling space?
Yes. Short straps let it hang under a 7 ft ceiling, and it mounts on a single ceiling joist or wall stud. Filled to 30–45 lb it sits well under residential load limits.
How are new designs chosen?
Every design is submitted and voted on by the community in The Lab. Top-voted designs are manufactured once pre-order funding thresholds are met — direct-to-consumer, no retail markup.
