Product Description:

Each package includes four high-quality masks, eight replaceable carbon filters, and eight exhaust valve replacements, ensuring you have everything you need for optimal performance and convenience.

Our sport masks feature replaceable activated carbon filters, which provide cleaner, fresher air with every breath. Instead of replacing the entire sport mask, you only need to swap out the filter, making maintenance simple and cost-effective.

Designed with user comfort in mind, these sport masks incorporate a somatological design with comfortable fabric, an adjustable nose pad, and an elastic strap. The adjustable nose pad and hanging ear design ensure a secure and personalized fit, while the elastic strap accommodates most face shapes and sizes.

The mask’s dual valves act as blockers to air, simulating high-altitude and low-air conditions. This design can enhance lung capacity training, making it a valuable tool for athletes. Additionally, the mask excels in windproof and dustproof performance, making it perfect for cycling, running, and other outdoor activities. Equip yourself with this versatile sport mask and experience unparalleled comfort and protection during your workouts and adventures.
