      Great sunnies, but a touch on the large side

      These are great CAT4 sunnies, which I bought specifically for use on the water. They work brilliantly and give great clear vision - I have another pair of CAT4s from a different brand and they give everything a very yellowed tint, not an issue with the Julbo Shields. The side protectors are a good addition although I have not needed then as yet. The only caveat is that these sunnies are on the larger side and the bottom of the frames sometimes rest on my cheeks causing sweat to accumulate occasionally. However they are held in place snuggly by the additional retaining strap which helps to counter this issue somewhat.
