ERETTUS CORE™ CONTINUOUS STIMULATION TECHNOLOGY
Designed for everyday use, Erettus Core™ combines multiple functional layers that work together to create the ideal environment for the male intimate area.
The Stay-Dry comfort layer keeps the skin dry and fresh, even after long hours of use.
Just below, strategic tourmaline points promote continuous, passive stimulation in the intimate area, helping to keep nerve endings active throughout the day.
This stimulation is intelligently distributed by a neurosensory layer, promoting constant communication between the body and the brain — an essential basis for a more predictable male response.
All of this is supported by an anatomical support base, which ensures correct positioning, stability and comfort without excessive compression.
It’s not just underwear.
It’s a daily solution designed to restore the male response over time.
Innovative continuous stimulation technology for male response
Erettus Core™ boxer briefs feature a multi-layered functional structure that acts directly on the male intimate area throughout the day.
This combination is designed to maintain constant stimulation, prolonged comfort and proper positioning, creating the ideal conditions for a more predictable and natural response.
No more uncertainty and frustration: feel more confident, more secure in your own body, and free to live your day — knowing that your underwear is working quietly in your favour.
The most practical and discreet therapeutic boxer shorts for male response
Designed for everyday use, from morning to night, Erettus Core™ boxer shorts offer the comfort of regular underwear, with soft, breathable fabric and an anatomical fit.
While you go about your normal life, its functional structure works continuously in your intimate area, helping to keep your body active, with total discretion and without interfering with your routine.
Feel more confident, more secure in your own body and at ease in any situation — knowing that your underwear is working silently in your favour.
Discretion and elegance in everyday life
Erettus Core™ boxer briefs are designed to offer absolute comfort and impeccable appearance in any situation.
The ultra-soft fabric ensures a pleasant feel from the first wear, while the anatomical fit provides freedom of movement throughout the day.
Completely invisible under clothing, the elegant design allows you to dress with confidence, without marking or drawing attention.
On the outside, they look like ordinary underwear.
On the inside, they work silently in favour of your masculine response.
⭐ RECOMMENDED BY SPECIALISTS
“Neuromuscular electrical stimulation is one of the most powerful, clinically recognised methods for restoring erectile nerve function — especially in men who no longer respond to pills. The Erettus Core™ is the first solution to integrate this level of stimulation into everyday wear, delivering continuous activation safely and effectively throughout the day.”
— Dr. Matt Franco, Male Pelvic Therapy Specialist (USA)
“Consistent neuromuscular stimulation restores nerve responsiveness, sensitivity and erection quality in a way medication simply cannot. The Erettus Core™ gives men a private, reliable solution that works daily — without systemic side effects or dependence on drugs.”
— Dr. Anthony Wells, Men’s Health Practitioner (USA)

Available in multiple sizes for a precise, comfortable fit.
Choose one pair to test — or multiple pairs to replace your everyday underwear completely.
Most men prefer ordering 2 or 3 pairs:
one to wear
one to rotate
one as backup
Because once you feel the difference, going back to ordinary underwear isn’t an option.
Every Erettus Core™ is designed for daily use, with durable materials built to last through regular wear and washing.
And for complete peace of mind:
You’re covered by our up to 90-day refund or exchange policy.
