Swedish company Malmsten AB and have had much influence on other swim
goggle designs as well. They feature a ready-to-assemble racing design
with a smooth seal and shatter resistant lens. Complete with string nose
bridge and double strap.
goggles are notable for a lack of a gasket or seal around the eye cup,
as found on most other goggles. They come in various colors including

irritating, not to mention dangerous! Low visibility can lead to
colliding with other swimmers, bumping your head on the wall, or banging
into the lane rope.
