Pepper Launches FDA-Cleared Dry EMS Suit, Targeting US Market

While electrical-muscle-stimulation suits traditionally require getting wet before use, Pepper’s version eliminates the hassle of water, which could drive higher adoption

Wearable fitness company Pepper is bringing its dry electrical muscle stimulation (EMS) suit, which is already in use across 30 countries, to the U.S. market.

The brand’s FDA-cleared dry suit uses electrical muscle stimulation (EMS) to tap into the body’s natural electrical signals. According to Pepper, the method activates up to 90% of muscle fibers simultaneously, as much as three times more than traditional training.

While EMS suits traditionally require getting wet before use so the electrical impulses conduct more easily, Pepper’s version eliminates the messy hassle of water for a cleaner, easier experience.

Pepper’s suit is marketed as a low-impact, full-body workout alternative able to provide the benefits of a 60-minute strength session in just 20 minutes, lowering the intimidation factor of picking up heavy weights and eliminating the need to have equipment at home for effective strength routines.

The company already ships to many international countries, and it’s now entering the U.S. market

“Traditional strength training remains out of reach for many, as it requires time, equipment, instruction, and a level of confidence that can feel intimidating,” said Pepper founder Emilia von Keyserlingk. 

“When I first experienced EMS, the results were immediately obvious, but the overall experience was complicated. It relied on straps, cables, a timely process of manually wetting parts of the suit, and a trainer to guide every session,” she explained. “We built Pepper to remove that complexity and make the experience simple and accessible, without compromising the effectiveness. You put on the suit. You press start. You become stronger.”

Here’s how it works: as users move through basic bodyweight exercises such as squats, lunges or Pilates-inspired movements, the suit delivers controlled electrical impulses, resulting in deep muscle contractions and activating muscles some workouts may never hit. 

The high intensity comes from muscle activation rather than external load, making for repeatable joint-friendly sessions made for all levels. The intensity is also fully adjustable, while the app guides people throughout each session to ensure safe and effective workouts.

EMS has long been used by physical therapists to stimulate muscles to flex and relax, a process meant to help “wake up” weaker muscles while boosting blood flow and promoting injury recovery.

Pepper’s wireless smart dry suit features 20 integrated electrodes made to replicate the body’s natural muscle signals, while its Powerbox — the central command center — controls when and how each electrode fires. The suit’s battery lasts about 10 workouts.

Additionally, the suit synchronizes in real-time with the Pepper app — which has over 100 guided workouts, no equipment needed — to sync the guided workouts and cue each movement at the exact moment the impulse fires for max muscle activation.

The system also features artificial intelligence to capture performance and wearable data that informs workout recommendations to each individual, adapting to user progression and strength gains.

Pepper isn’t the first brand to innovate EMS dry suit technology. Boutique fitness franchise Body20’s workouts are based on its own EMS dry suits that condense long gym sessions into 20 minutes, although Body20 doesn’t sell its suits for at-home use.
