The style isn't for everyone, and I know they're not polarized, but it's tough to find a decent deal on any Oakley sunglasses [ashford.com]
with their golf-specific lenses. These are their "Prizm Dark Golf," which is better for brighter environments than their Prizm Golf.
I bought these, and they came with an impressive hardshell case, perfect for safely storing them in my golf bag. I didn't expect that, but it was a pleasant surprise.
There may be some free shipping codes floating around to waive the Ashford's pesky $6 shipping fee.
