The Smiles Run Jacket is an ultra-lightweight running jacket weighing just 55g/m², built from 100% recycled nylon for wind and light rain resistance without unnecessary bulk. An adjustable hood, side vents, and hem straps allow runners to dial in fit and airflow across varying conditions. Three pockets — two side and one back — provide practical storage, while the packable construction makes it easy to stow when conditions improve. A reflective UNNA logo on the back adds low-light visibility, and the PFC-free finish keeps the jacket environmentally responsible.
