Just got the Smartwool boxer briefs I ordered.

Very lightweight, nice for summer.

However, be warned, Smartwool's "Large" is a good bit smaller than Ibex's "Large." And like all of the Smartwool clothes I've encountered, not quite as nicely made as Ibex and I'm not expecting them to be as durable as Ibex. But not bad at half the price of Ibex.
