Tank Skin Layer P1 - Women's

What Our Gearhead® Experts Are Saying:

“For hot races or long training blocks, this is one of the best baselayers out there. It vents heat incredibly well and fits tight without feeling restrictive. The seamless body and raw armholes make it perfect under aero jerseys or hydration packs—zero rubbing, zero bulk.”

The Assos Tank Skin Layer P1 is engineered for riders who demand high-efficiency thermoregulation in the heat, whether they're tackling multi-hour endurance rides or racing at threshold. The Circular Seamless mesh construction boosts breathability and cooling airflow by maximizing exposure to moving air while maintaining a stable, body-wrapped fit that excels beneath tight aerodynamic jerseys. The carbon-infused fibers provide permanent odor control, making it ideal for back-to-back training days or stage races.

The deep-cut collar interfaces cleanly with both regularFit and racingFit jerseys, while raw-cut armholes minimize bulk and friction beneath shoulder seams and pack straps. The baselayer’s ultra-elastic makeup ensures total freedom of movement without sacrificing its low-volume structure, supporting consistent moisture transport during intense climbs and sustained tempo efforts.

Designed for serious cyclists who value precise layering and heat management, the Tank Skin Layer P1 delivers a truly seamless integration of comfort, performance, and minimalist engineering.
