Face Mask,Supersafe 2-Layer, Washable, Reusable by 4DflexiSPORT

✈️Your Essential Travel Shield: A face mask engineered to safeguard you, the wearer.

Superior Protection for every outing. Confidently navigate high-exposure environments and travel (plane, bus, train) with our next-generation, science-backed mask. Washable, reusable, and built for comfort.

✨ Double Safety Confidence: The 4DflexiSPORT Difference

It's not just about filtering; it's about intelligent engineering. We utilise the latest scientific findings—echoed by researchers Loretta Fernandez and Amy Mueller—which state that masks must slow down viral transmission through complex air paths.

• Scientific Design: The 4DflexiSPORT mask adopts this principle through its woven, maze-like 3D spacer fabric construction.
  
  
• Double Layer Filtration: By using two layers of this specialised fabric, each with built-in vapour-resistant filtration, we deliver superior protection that remains easy to breathe through.
  
  
• Reduced Risk: Reduction in exposure to high viral bombardment is key to lowering infection risk. As Harley Street consultant Mr. Ian Bayley (FRCS) notes, "over time we'll see this new concept mask used more and more in medical circles."

✨ Comfort and Fit for All-Day Wear

Designed for prolonged use without compromise—as testified by professionals in demanding environments:

• Trusted Comfort: Endorsed by barristers wearing it all day in court and utilised by surgeons in the operating theatre, proving it is surprisingly effective and comfortable for continuous wear.

• 3D Moulded Structure: Stands clear of the nostrils and lips, ensuring:

  • Easy, clear speech.

  • A comfortable, non-claustrophobic fit.

  • Lipstick-safe for ladies!

• Superior Seal: Forms a comprehensive seal around the face—unlike throwaways—preventing gaps at the sides that allow viral particles to enter the respiratory system.

• Anti-Fog System: A crucial bendable metal strip seals securely over the nose, preventing glasses from misting up, eliminating discomfort, and demonstrating the containment of warm breath.

Durability & Washing

When the correct care instructions are followed, your 4DflexiSPORT® face mask is highly durable and designed to last wash after wash.

• Reusable Indefinitely: Machine or hand washable (30°C or 40°C).

• Washing Caution: For extended longevity and to minimise the risk of residue buildup, we highly recommend hand-washing your mask with a mild, unscented detergent. If using a washing machine, place the mask inside a laundry bag to minimise friction and aggressive folding.

Important Disclaimer: Metal Nose Strip

The bendable metal strip is designed to create a custom seal over the nose area and prevent fogging. To ensure its durability:

• Minimal Adjustment: The strip is intended for minimal adjustment—specifically, closing any gaps near the nose when the mask is first fitted.

• Avoid Rough Handling: Constant opening and aggressive closing should be avoided, especially during washing. Rough handling and frequent folding/unfolding within a washing machine cycle can contribute to metal fatigue and potential breakage.

Note on Returns: We cannot take responsibility for breakage of the aluminium metal strip resulting from metal fatigue. The mask remains a highly effective face covering with or without the metal strip, and breakage does not constitute a reason for return.
