OXYGEN ADVANTAGESPORTSMASK | Designed by Breathing Expert Patrick McKeown | Altitude Training at Sea Level | Training Mask, Fitness Mask & Sports Mask

Brilliant product thank you

Excellent product amazingly effective solution for altitude training.Good seal around face to force compliance with restriction level you've chosen.The straps are quality material with proper Hook&Loop strips as clasping.Just a very thin material so you'll need to careful attaching and more importantly when taking this device off at end of workout.The good in the material is that if like us you're riding with this!!! You can use you jaw to ease restriction temporarily if needs must.The additional information and tutorials are TOP NOTCH from a demonstrably qualified professional and inventor.Buy in confidence.

These masks are amazing to wear but you do get some strange looks on the street when wearing them. Although the Covid situation makes it more acceptable. I bought two of these. One for a woman and one for a man. They fit perfectly. After some adjustments. Would highly recommend

Comes with an excellent instruction Manuel . This type of breathing has changed my life . I’ve always competed at a high level in several sports . This las year had been a torrid time . 5 Ambulances ( all after high intensity cardiovascular output), MRI’s , ECG,s Cardiograms and so and so . I read Patrick’s Book had a bolt score of 12 . One month later I feel like my old self. Training is easier. I’ve lost 8kg . I’m sleeping better . I’m easier to be around ( my wife tells me ) This morning my waking BOLT score was 41 . Thank you to Patrick and all of you at OXYGEN ADVANTAGE . Johny

I started slowly, using this at home while sat to gradually improve CO2 sensitivity. I then started walking in the mask too. I noticed differences - better sleep, calmer, more energy, noticeable diaphragm workout.Update - I did have a few issues in terms of the product coming apart, so could be a little better construction.

Was looking forward to training in thisThe seal around the edge has been sealed at an awkward angle so doesn't fit on face correctly and leaks air and falls off faceReally disappointed

Highly recommended for Nasal Athletes

This is one of the cheaper masks i have purchased but seems to be the best, very comfortable fit, light weight. All my previous masks have required me to change parts etc to adjust the settings, this mask is so easy to change the settings, just by moving the slider across on the front of the mask,The only issue for the 4* and not 5* is the rubbery plastic smell while using the mask, but i am hoping this fades the more the mask is used/cleaned
