Alas this is a rare instance where simms have not given enough thought to the product? I am currently out in the Seychelles on one of the Atolls there. We are fishing 8 hour days in the blazing sun and alas sun protection factor 30 for a garment just is not even close to being sufficient. Even the guides here are using 50+ sunscreen as a minimum and I and many of the others in the party are still burning using the same. For a truly effective tropical fishing shirt, the protection factor needs to be way higher than only 30. Maybe great on a dull day, but under normal tropical conditions, noone should risk using the shirt and burning their torso believing that they will be ok. Dleighted to chat the issue throgh further with the company

This shirt is super durable. Used all season with no wear issues- cleans up easy. Even had a bad tumble and fabric did not tear or rip. Also great placement on the pockets- just enough.

This is a must have shirt for fishing in the tropics.Very breathable and protects you from the suns harmful rays. The subtle colors don't spook fish while on the bow casting.
