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