【airhead】Ventilation Liner for Helmet [Rising Sun] Review

Good for circulation? Is it?

I've heard that it tingles and is good for circulation, but is it a compromise? Not for me.
The tingle was really tingling and painful, so I gave up after 10 minutes.
I guess it depends on the type of head Large Kisa Helmet. Impossible View detail

I think that it is quite good.

This is the second time I have purchased this product.
The last one I bought was also used for 5 years, but I had no problem with it, and I changed my mind with a new Helmet.

I think the durability of the product is fine, and the stinging at the beginning of wearing is a good thing if you think of it as a blood circulation booster (laugh). View detail

I'd say it takes about a half hour of use to cause distress (pain).

Pain occurs after about 30 minutes of use.
My hair is disheveled, but I can't bear the pain.
I've tried to wear it in my own way, but I'm limited to wearing it for 30 minutes.
I think it is good if it is a loose Helmet, but a Helmet that fits
30 minutes seems to be the limit.
Please consider your purchase carefully. View detail

Unfortunately, it works, but it's not painless.

At first, it was good, but after about 30 minutes, my head began to hurt and I realized that I could not use it for a very long time, which was disappointing.
I shifted the position of the device to see if it would improve somewhat, but after some time, it became very painful. View detail

The haircut is not flattened, but the protrusions feel painful after prolonged use with Two-Ling. View detail
