Key Features
Half designed; half engineered – the Slimtum® Original waist trainer is the ultimate shaper. The level of materials and performance that go into this waist trainer is unparalleled. Featuring our Supercore™ shell material, our Superflex™ bones and a host of custom materials and construction techniques, the Original was built to perform. Comfortable enough to wear all day, firm enough to snatch your waist up, stylish enough to wear for fashion in its own right – our Original is the waist trainer you pick up when you’re serious about shaping.
Product Details
Superior Shaping Performance
We custom manufacture the Slimtum® Original for one basic purpose: Superior waist shaping. Every bespoke component is optimized for this goal. Our Supercore™ material is the result of years of experience and development in composite materials for waist training. This proprietary material forms the main shell of our Original waist trainer and provides elasticity, stretch %, tension, hardness/softness and figure conforming properties that make it ideal for waist training. The cut of the Original is aggressive and provides the optimal balance of tight fit and comfort. External shaping bands add to the shaping power over the critical ‘love handle’ and lower belly areas, while the full coverage makes sure the waist trainer contacts and shapes the whole midsection.
Surprising Comfort
There’s no point having an aggressive waist trainer if you can’t wear it for long hours. When designing our Original model, we took great care to ensure the garment is as comfortable as possible. For comfort, we use our special stretchy binding to ensure it doesn’t pinch your skin, a custom smooth liner to reduce friction while wearing, our proprietary Superflex™ boning that conforms to your body while supporting the garment shape, a subtle comfort contour on the under bust edge and our proprietary Supercore™ material.
Ultimate Durability
The Supercore™ material used on our Original waist trainer is extremely durable. The synthetic parts of the composite are sweat resistant and the entire composite can tolerate thousands of stretch-return elastic deformations before showing signs of wear. Our proprietary Superflex™ boning has a very high degree of kink resistance, so the garment retains its shape even after scrunching and other abuse. Careful construction techniques ensure key points of failure have been reinforced with the appropriate stich methods and materials.
Expert Waist Training Shape
The Slimtum® Original features an aggressive, yet comfortable shape that our lead designer has created from years of experience in waist training. The cut is balanced together with the external shaping bands and the specific stretch properties of our Supercore™ composite shell to provide a superior shape. This is the same shape worn by the top fitness and aesthetic athletes in the world.
Subtle High-End Styling
Rich blacks, figure flattering lines, subtle accenting and logo marking make the Slimtum® Original a seriously stylish waist trainer. A level of subtlety and care in the treatment of styling elevates the garment into the high-end category. The result is a surprising waist trainer that looks at home whether coupled with your gym set or even your chic, designer items.
Extended Full Coverage
Our Original waist trainer is designed to deliver superior shaping across the whole midsection. This ensures the highest level of shaping performance as well as a perfect presentation from the top to bottom of the waist and abdomen.
Discreet Low Profile
The internal bones on the Slimtum® Original make for a stiffer shaper, but also allow us to present a perfectly smooth exterior. Coupled with our tough but thin Supercore™ composite, our Original fits flatteringly under most external garments.
Sizing
We use single measurement sizing for our waist trainers – measured around your small of waist.
To find your size, wrap a measuring tape around your small of waist (as shown in the image). Look up your small of waist measurement in the SMALL OF WAIST column in the chart. Find the range your measurement fits in. Your Aero 2™ waist trainer size is in the SIZE column to the left of the appropriate range.
NOTE – WE HAVE SIZED OUR WAIST TRAINERS ACCURATELY to work for your current small of waist measurement. Please order the size of waist trainer shown as smaller sizes will not fit.
NOTE – OUR EVERYDAY WAIST TRAINERS DO NOT MATCH THE SIZING OF OUR PRO WAIST TRAINERS. Please size your Original separately to your PRO.
Care Guide
Made from a Supercore™ shell, the Slimtum® Original can be washed just like normal clothing. To wash our Original waist trainer; place it in a wash bag and put it in a regular wash with your clothes. After washing, we recommend air drying as the quick dry fabrics will dry fast even with air drying. The Supercore™ material is very resilient and can also be machine dried. Machine drying once every week or two is good for the fit and feel of your Original waist trainer.

FAQs
What’s the difference between Slimtum Original, Aero and Pro?
Original provides strong everyday compression, with a longer profile and external V-Tape for additional waist shaping.
Aero is shorter, lighter, and more breathable, making it our most comfortable option for everyday and extended wear.
Pro is specifically designed for training, providing stronger support during heavy lifting, leg days, and cardio.
Many customers use Aero or Original for everyday waist training and Pro for their workouts.
Can I wear Slimtum Original for training?
Original is primarily designed for everyday wear rather than heavy training. You can use it for light upperbody work out (shoulder, back and chest) For weightlifting, heavy leg days, and demanding workouts, we recommend Slimtum Pro.
How tight should my Slimtum Original feel?
It should feel firm and noticeably compressive without being painful or restricting your breathing. Stronger compression does not mean you should force yourself into a smaller size.
Should I size down for more compression? Will it make my waist smaller?
Original is our stronger everyday waist-training option, designed to help shape, define, and maintain a smaller-looking waist with consistent wear. Its longer profile and V-Tape provide targeted additional compression for a more sculpted silhouette.
Original already provides strong compression by design. Choosing a size that is too small can overstretch the garment and reduce its lifespan.
Consider sizing down once you can comfortably wear your Original on the tightest row for around 4 weeks, consistently wearing it 5–6 days per week for 6–8 hours a day. Check our size chart again before moving to the next size.
When should I wear Slimtum Original?
Original is designed for everyday waist training. Its firmer construction and longer profile provide stronger, more consistent compression throughout the waist.
How long should I wear Slimtum Original?
Build up your wear time gradually. Once comfortable, Original can be worn for 6–8 hours a day, 5–6 days per week as part of your waist-training routine.
How do I wash my Slimtum Original?
Hand wash in cold water with a mild detergent. Air dry naturally in a well-ventilated, shaded area. Do not machine wash, tumble dry, bleach, or iron.
How do I keep my Slimtum Original in good condition?
After training, allow it to air out completely before storing. Hand wash when needed and avoid high heat, machine washing, or excessive twisting.
