The 3L Nano Jacket is built from a lightweight, air-permeable 3-layer fabric engineered around the competing demands of running in the rain. Its membrane keeps water out while allowing heat and moisture to escape as effort rises, with air permeability improving comfort at running intensity.
Fully taped seams seal the construction against rain, while a C0 DWR treatment helps water shed from the outer face. Together, they create our most protective waterproof shell without compromising the breathability needed to run hard in wet conditions.
Raglan sleeves and a streamlined cut keep movement unrestricted. A single-cord hood draws coverage close around the head, with a Napoleon pocket providing secure storage and reflective detailing adding visibility in low light.
