“…simply the best base layer…”
SheCycles.com tests X-Bionic UnderGear - this is what they say:
We tested the X-Undergear in a variety of conditions from serious sub-zero temps to warmer winter days when sweating was more of an issue than getting cold. Which ever you choose to ride in the X-Underwear, it performed suberbly, infact we’d be happy to standby our claim that it is simply the best base layer we’ve ever had the pleasure of wearing.
Super technical with an amazing fit the X-UnderGear shirt opens up new horizons for base layers
