    Mask from Atlantis
    Great fitting and visibility as well as colour. None

    Perfect mask both in the pool and open water for underwater swimming. Portable enough that it sticks nicely in the side of my swimming briefs when carrying them. Definitely one of the besk scuba masks I've bought in a long time.

    Comfy head band Leak after a couple of minutes around the nose pie

    Only OK for casual use but did leak after a couple of minutes. Same for the one bought by my son
