Whatever you do, don’t call it underwear. Our Airborne LS 2 long sleeve base layer shirt is so much more than just that. Made with incredibly stretchy, hypoallergenic Dryarn®, soft-to-the-touch fabric and constructed using 3D round knitting for comfort-assuring, minimal seaming, the Airborne LS 2 puts base back into base layer. The form-fitted, long sleeve shirt truly is the foundation of any road-ready outfit.Keep you feeling cool and freshBy engineering specific fabric structures into the Airborne LS 2’s design, perspiration is wicked away and allowed to evaporate effectively and quickly, to keep you feeling cool and fresh however demanding conditions might get. On top of its heat-regulating properties, the Airborne LS 2 base layer also prevents your top layer jacket from sticking to your skin. That makes taking your gear off after a long day’s riding in high temperatures much easier. Throwing your base layer in the washing machine is also a great deal simpler than washing your jacket. So, your favorite riding jacket keeps feeling fresh for longer.
