Elevation Training Mask 2.0 Medium (140–180 Lbs) Resistance Mask®, High Altitude Mask, Workout (Black) Check Size Guide Before Ordering

No es nada comoda, pero funciona bien, hice tres series de tres minutos para probarla mientras caminaba y me gusto, ajustar la altura es fácil, pero ya que pusiste la tapa de la altura seleccionada no se puede cambiar a menos que te quites la mascara y cambies la altura. Compraria de nuevo.

Great fit. Works for what I need.

It does put a lot of pressure on the bridge of my nose. After a while of wearing it I get used to it and forget about it, so it’s not too bad. If you have a beard, be aware there’s limitations with this mask! I have to essentially block all airflow to the mask to get a really strong negative lung pressure. It ends up working pretty well, but I imagine it works better without a beard. Only real complaint I have is that it doesn’t really strap great behind the head and it ends up pulling on my ears. Makes it tough to wear ear buds. But all in all, it’s doing the exact job I need it to do, so I’m still using it constantly!

Great mask that doesn't let a bunch of air blow into my eyes on every exhale. This one fits tightly over the bridge of my nose, and is made of thick durable material to ensure a tight seal. The version I bought came with a variety of seals and an over-head strap that provides plenty of customizable solutions for workouts, along with the dials that allow changes in resistance mid-workout. I greatly appreciate this decision to let the customer choose.

It fits pretty well and has the looks and the feel of a very well made product. However, it makes a lot of wheezing and high pitch noise that I’d be too embarrassed to wear it while working out. I just hope I can return it
