With and without the UV resistant layer
A side by side comparison of two sails about two years old:
This sail is on John Simon's Aeros Combat C 12.7. It does not have a UV
resistant layer. John is getting a new sail that will have the UV resistant
layer, hopefully on top on the outside.
This is the Wills Wing T2C 144 that I fly. There is no UV damage that I can
detect and the sail is in excellent shape.

This is consistent with our experience comparing off-the-shelf
laminates with our custom laminates produced with UV-stable-film
Any laminate without UV film becomes brittle with cracks and flakes starting in
the outer layer in as little as one year of harsh UV exposure. UV film doesnt
become brittle with 5x as much exposure (although it is still subject to
scratching and wear-and-tear). The problem remains that most manufacturers claim
that their laminates have UV protection which is misleading at best. Anything
other than special-order UV film is ineffective at extending the life of
laminate sails. John Simons sail material has UV-protection but it does not
have UV film.
