I've taught skiing since 1992, and have worn Bolle's since 1993. LOVE them, especially the RX adaptor... maybe it's my local optical store, but mine was able to lower the bifocal part to account for skiing needs. They also worked so well for Keeping people safe as they rode the trams at Indianapolis Motor Speedway, as I worked there for 10 years straight, also... w/o great sunglasses, that job would have been a horror. With them, it was a pleasure.
Pros: versitility/quality/ease of use
Cons: none
