Floating carp fishing glasses.

Most sports sunglasses are 'lightweight', but the fact is, almost all of them will sink without a trace if you drop them over the side of a boat, or in a river or lake. Rapid Eyewear's polarised fishing sunglasses that float, weighing in at a paltry 10g, do exactly what it says - they are floating sunglasses. With polarised, Frostech blue mirror lenses, they look attractive, are tough and most importantly, float will do the job you need on the river bank, lake or ocean.
