The Men's Solution 150 Baselayer Bottom is Black Diamond's solution to skiing all winter long, regardless which side of the rope you prefer to ride. Its merino wool blend excels at thermal regulation and odor control, and unlike most merino wool baselayers, the Solution utilizes Black Diamond's Nuyarn technology to enhance strength, warmth, and quick-drying comfort. The bottom wicks moisture when you're sweating on the skin track, and warms you up when you cool off on the ride down.
