An exceptionally light base layer that manages moisture & controls odor beneath second-skin cold-weather layers or as a standalone top during indoor training. Thermal weatherproof equipment is no longer the bulky PVC rain capes & adapted ski jackets of decades past so—at the request of our World Tour riders—we tailored a long-sleeve base layer to provide summer-worthy wicking & odor control that fits unobtrusively beneath race-tuned equipment like our Spring Fall Jersey or Jacket. In cool or cold weather transporting internal moisture is as important as keeping the external elements out especially during intense training or racing when a series of intervals hill repeats or attacks can lead to lingering moisture a clammy chill & frigid misery. Alternatively full-arm wicking is a must for indoor training when moving through the air isn’t constantly keeping your arms dry. WHEN/HOW TO USE IT Layer it under insulating weatherproof layers for fall winter & early spring; for indoor training layer it under your bib straps & omit the jersey altogether. 89%PP 7%PA 4%EA
