X‑BIONIC^® ENERGY ACCUMULATOR™ Functional Underwear

High Compression for Increased Power During Sports

X‑BIONIC^® Functional Underwear uses the body’s different heat zones to regulate its climate.

Enhanced Performance Without Doping

Our bodies produce different amounts of heat in different places. X-BIONIC^® UnderGear reacts to this with pinpoint precision and supports the body in maintaining its preferred 37ºC temperature. The first proof comes through a regulated release of warmth without the risks of overcooling: you conserve precious energy for ability to perform.

Reduce Sweat, Do Not Prevent It

Do not waste a single drop: sweat is too precious to dispose of completely. Our skin needs moisture to cool itself down. Moisture must first vaporise on the skin before our body temperature can be reduced. Traditional active undergarments do not account for this. They absorb moisture in its entirety and keep the skin as dry as possible, a mistake. Dry skin feels good, but it does not cool.

Cools When You Are Sweating

The cooling effect of X-BIONIC^® UnderGear is only activated once you start sweating. Its clever regulation system works with the most reliable of starters: your sweat. X‑BIONIC^® UnderGear is one of a kind, effective, and always just in time with its cooling power. Regulated climate control, developed by scientists, tested by endurance athletes.

Keeps You Warm When You Are Cold

You know that unpleasant feeling of having just sweated and then getting goose bumps afterward. Your body is sounding the alarm: Caution, overcooling risk. X‑BIONIC^® Functional Underwear prevents these chills. If no sweat is present, then a unique process uses air heated by the body as thermal insulation.
