Utilizing the same design technology employed for its high performance baselayers, Icebreaker infused the Men's BodyFit 150 Ultralite Anatomica Boxer with all the same comfort and functionality. The super soft jersey knit merino wool is very lightweight, breathable, and its anti microbial properties fight odorsgreat if you're working up a sweat or on a backpacking trip where you need your undies to last for the long haul. And for less adventurous days, these same features make for all day comfort. A little bit of Lycra adds stretch for a contoured fit, the satin jacquard waistband keeps things secure, flatlock stitching prevents chafing and a contoured pouch with fly makes things easy when nature calls. After being spoiled with this level of high performance comfort and easy functionality, you'll have a hard time settling for anything less.
