These boxer briefs are designed with your comfort and peak performance in mind. Woolpower LITE's fabric delivers a sublime balance between the insulating and moisture wicking properties of Merino wool and the durability of synthetics. The result: a true performance boxer brief that should never be left behind. Woolpower LITE is our thinnest fabric. It is a cool and comfortable material that is best worn nearest the body. LITE is tight knitted and therefore cooler, even though it actually contains more wool than our undergarments made of UllfrottA Original. LITE is good for using in slightly warmer conditions, as the fabric helps to cool down your body. But it also keeps you warm when it's cold out.
