Build respiratory strength – with four adjustable resistance levels
Four adjustable breathing levels alter airflow resistance so inhalation and exhalation feel progressively harder, allowing real-time intensity changes during exercise. Settings can be modified without interrupting the routine.
Graduated resistance increases respiratory muscle workload over repeated sessions, helping improve breath control during high-intensity training.
Comfort for longer sessions – with lightweight silicone and breathable mesh
Lightweight silicone construction pairs with a wider breathable mesh to reduce facial pressure while permitting airflow. A strong sticky fastening provides an adjustable fit for different head sizes.
Lower discomfort during sustained effort and a secure fit help maintain focus on training rather than equipment.
Portable altitude-style training – with a versatile sports-ready design
Compact silicone build and instant resistance adjustment make the mask suitable for aerobics, running, cycling and gym workouts, enabling simulation of altitude conditions wherever training takes place.
Carry-out sessions mimic higher-elevation breathing to challenge respiratory mechanics without travelling to different locations.
