Adurance High Altitude Training Mask

Fits well and works great! Better than expected! The straps are comfortable on the hear and over the ears - this fit my 13 year old girl just fine, and the universal size surprisingly works for both our heads. Like the adjustability of the breathing restriction. It does get sweaty inside - as expected with a work out. But like that the rubber and plastic parts seem easily washable with soap %26 water, and the fabric part is a quick drying material. Hoping this training use will help us go from sea level to the high altitude competition!

Bought for my nephew. Exactly what he was looking for at a good price. Fast shipping.

item was missing from box

So far so good! I wore it for 10 minutes and I was definitely breathing deeper after the experience! I'll gradually increase the time each time I wear it!

I bought it for my dad that does iron man and spartan races and he trains with it all the time. He said it's really hard even on the first setting.

It specifies for men. I am a woman with small face %26 this mask helps with lung issues. Be more beneficial if it came in sm, medium %26 large. Not all faces are the same

Should have bigger straps

The product works very well and the price is great. Simulates climbing high elevation as well as could be hoped without spending hundreds. Unlike another review here, I found the size to be perfect even though my head is large (one strap is "set" and the other is adjustable). One note of "caution", just like an N95 mask or other face covering, having a beard will essentially negate the effects because air will get in through the space between the mask and face. This is no fault of the manufacturer obviously, just simply how airflow works - just be aware if you have a beard, no such face covering will work most likely.

It broke after the first use

like I especially like the adjustable valve on the mask very high quality!
