Icebreaker's Beast Brief uses a delightful blend of merino wool and stretchy Lycra to keep your loins comfortable and under control. A closed, contoured pouch cradles your goody basket for ample support, and the athletic cut gives you plenty of freedom to roam the wild without feeling restricted. Merino wool naturally repels odor and wicks moisture away from your skin to help keep you dry while you wrestle with the elements in Man Vs. Nature style. So grab ahold of the three centimeter elastic waistband, pull these undies over the family jewels, and loudly proclaim your manlihood with a blood curdling roar—nice work; women and children are fleeing.
