Mask and tube are made qualitatively. Came from the russian federation for 6 days. The main thing that you need to know people with a thin and small face, this mask is not for you! The smear space is small and it's good, but if you have a small and thin face, know: if you want to check whether this mask is suitable for you, you may encounter the same as me problem (the mask does not fit tightly and does not sit to the face, even if you draw the air with your nose), If you want to tighten the strap-the mask will strongly press on the bridge of the nose. In the water head down the mask with a tightened strap does not yet miss, but if you want to look up or swimming up the face, the mask is likely to miss! If possible, i will check again on the big water and add feedback.
