He ordered monogrammed beer mugs from the Pottery Barn.
They're a pretty solid groomsmen gift, after all what guy doesn't like to drink beer? These ones in particular are a nice heavy weight, and the monogram is a nice, deep engraving. I know the boys will love it.
I also wanted to highlight one other cool groomsmen gift idea, something I bought for Mr. B and his brother. Etsy seller HandySam makes really cool, well-designed wall mount bottle openers:
(Personal Pic)You pop the top off your beer and the cap goes into the cool vintage can, and to empty, you can just twist the can upside down. So cool!

The seller was unbelievably fast (I got these three days after ordering them), and also offered me a discount (full disclosure, I asked for one. I always ask if I'm buying multiples of an item. I've never been denied).
Combine these with some cigars or a nice bottle of liquor (or just do them by themselves) and I think you have a very nice groomsmen gift!
What did your guy do for his groomsmen?
