Adurance Training Workout Mask, 4 Breathing Oxygen High Altitude Training Mask Exercise Device

I have the biggest head of all the people I know. This thing fits tight, yes; however, that is the entire point of this mask. If it didn’t have such a tight hold then I wouldn’t be getting air from the mask but from the air pockets on my face in between the mask. Mask fits massive faces perfectly.

Well designed and fits well on my small head. The setting are easy to adjust, and it feels effective as long as it seals to face properly. I used it in the Caribbean to train for a trek up Mt. Kilimanjaro which I begin next week. That will be the real test.

It’s a beautifully engineered mask. I did really like the overall design. And (4) different settings is impressive. It’s just too small for me. I’m 6’2” and 220 lbs. It feels like it was made for a smaller man’s face. If I could get a bigger size, I would.

I have a “small” adult head and the straps on this mask seem to fit a toddler’s head . The reason I say this is because I’ve had breathing mask before and the fit was “comfortable” . Even after adjusting the mask at all angles of my head, it’s still a tight and uncomfortable fit . I DO NOT recommend!

I've bought from the company before and it's made a huge difference in my endurance and training for hiking in the mountains. So when I saw it on discount, I thought I'd replace the previous one that I wore out and more. I'd had one before and thought, why not?It came in quickly and immediately saw a problem immediately. . Whoever made the harness for the head... has never seen an adult human head before. I couldn't even get it on! It's like it might fit a child's head, it's so small. It serves zero purposes for an adult if you can't get it over your forehead, much less anywhere else. Secondly, the previous version had a velcro patch on the back, to fit on the head. This one doesn't. The elastic is non-existent and, to be blunt, not even worth returning (since shipping costs are outrageous right now.) I figured I'd save someone else the hassle and bin it instead.I gave it 2 stars since I did see the mask part, where the O2 restriction is, is exactly like the old ones. That's the only reason this isn't a 1 or zero-star review.So now I purchased another from a different company, at full price, since fall hiking season is coming and my last one was binned.

Easy to adjust resistance whilst working out, the variance is perfect and the price is much less than many of the competitors. I have other brands that cost more and find myself using this one the most.Using it daily so well used

Definitely is an effective training mask. We like the four different settings, found it difficult to do much with it on the 4th (hardest) setting, which is the goal with the training mask. Better mask than other similar products we have tried before. Comfortable to wear as well.

It literally restricts the amount of air you take in, rather than the density of oxygen in the air you intake. Good if you are intermediate-advanced track athlete and are looking for a challenge.

The mask limits o2 as described but the head strap is incredibly tight and almost unusable.Bear in mind i have a fairly large head but, i doubt my cheeks billowing out of the sides of the straps like a chipmunk was a intentional design choiceFor the price, im happy to cut the straps and add some length and velcro

Hello,I decided to returned the product because due to the quality issue of the silicone mask which has a bad wrinkle and it won’t fit on the face because the mask fitting won’t settle on its original form. My advice you need to pay attention to the mask quality issue. The designed was quite good and simple good looking overall, except the mask quality issue (bad wrinkles won’t settle back on its original form or mold). I would happy to re-order the product if the issue will be fixed and will recommend to others.A serious advice.

The mask's not worth buying, strap is too short making it stuck to your face permanently, at least it ain't budging. When putting it on, I can barely breathe through my nose, it just doesn't fit every skull at all but training with it I can tell does improve something, makes you work harder for every breathe you take. Honestly though, just any product that limits your oxygen intake doesn't seem that worth, it was pretty cheap though, I'll give it that and it can make any man look like Bane.
