Description

The PROTON SL HOODY for men from Arc’teryx is a lightweight insulating jacket designed for intense mountain activities, especially climbing and technical outings in changing weather.

It combines excellent breathability with targeted thermal protection thanks to Octa® Loft insulation, which retains heat while limiting the build-up of moisture during exercise. The exterior fabric Fortius™ Air 20, at once resistant, stretchy and breathable, ensures optimum freedom of movement and durability suited to demanding environments. The FPAS-free FC0 water-repellent finish helps repel light moisture, while the helmet-compatible, insulated and adjustable hood enhances protection against the cold.

Its fitted cut and articulated design make it a versatile piece, ideal as an active or mid-layer.
