Kleinsub - F1

Kleinsub F1 Low-Volume Freediving Mask

The Kleinsub F1 is a low-volume freediving mask with an internal volume of just 85 cc, equipped with clear, transparent resin lenses featuring UV-400 protection and anti-fog treatment. This ensures sharp and clear vision throughout your entire dive.

Crafted from 100% pure, food-grade liquid silicone, the mask offers a snug fit with a double feathered skirt that effectively prevents water from entering around the eyes and nose.

Its ergonomic design is tailored for medium-sized face shapes, ensuring a comfortable and stable fit. The mask also comes with a flexible silicone strap and a quick-adjust buckle, allowing you to easily customise it to your head. With an impressive 120° wide-angle field of view, you’ll enjoy exceptional peripheral vision that takes your freediving experience to the next level. The HD lenses complete the clear, crisp view, making this mask an excellent choice for both beginners and experienced freedivers.

Care Instructions:
Resin lenses are delicate and require gentle handling. Avoid wiping them with cloths or microfiber, and never use baby shampoo, anti-fog sprays, or other chemicals. Always rinse the mask thoroughly in fresh water after use to remove salt and debris.
