Mens Nuclei SL Jacket
This product is not available

An intelligently designed belay jacket that provides alpinists and climbers with three-season warmth for minimal weight, the Arc'teryx Men's Nuclei SL Jacket utilises the lightweight performance of Coreloft 60 synthetic insulation, ultra-lightweight Arato 10 nylon fabric, and highly efficient ergonomic patterning to deliver performance in a jacket that packs smaller than a one litre bottle and delivers effective warmth for a mere 255 grams. A DWR (durable water repellant) treatment and the synthetic insulation's ability to retain warmth when wet make this a versatile choice for the shoulder seasons' damp, dripping belays.

Articulated patterning and gusseted underarms provide extended mobility without sacrificing coverage. The trim fit accommodates light layers, but stays close to your body for a higher level of thermal efficiency. Arc'teryx' e3D (ergonomic 3-Dimensional) patterning utilises extra space in key joint areas to bring an added level of use specific articulation. Simple elastic binding around the cuffs is light, streamlined and creates a secure fit.

The insulated hand pockets are positioned to stay out of the way of hipbelts and harnesses, and employ minimised zips to shed grams and streamline the jacket's profile. Secured in a pocket, the included stuff sack can be easily removed and clipped to a harness or pack. The No Slip Zip secures the closure with a series of small bumps spaced every twelfth tooth to hold the slider and prevent self opening, but still unzips with a single hand for rapid ventilation.
