Ex Officio made the Men's Give-N-Go Boxer Brief so great for travel that you'll want this 2-Pack. This highly breathable boxer brief wicks moisture and dries quickly, while an Aegis Microbe Shield treatment helps the Give-N-Go resist odor. Ex Officio added Lycra for a four-way stretch that excels on hiking trails and climbing walls. The Give-N-Go is also easy to wash, whether you only have a sink or a stream.
