Zone3 Under Trisuit Briefs are designed as comfortable underwear that provide gentle support and comfort when worn under triathlon clothing. Thanks to the seamless construction and ultra-light elastic material, they perfectly fit the body like a "second skin", minimizing friction and increasing comfort during longer training sessions and races. These briefs are ideal under a triathlon trisuit, bib shorts or leggings, but are also suitable for separate wear during other sports activities or as a bottom layer for everyday wear. The material wicks away moisture and supports body temperature regulation, so you feel comfortable in them even during intense exercise.
