Crisp fall mornings, cold winter days, the chill that sets in when the sun falls below the ridgeline – when temperatures drop, you need to pull on something warm. Simple, versatile – and warm – the Covert Pullover gives you the thermal performance of our Alpenex™ II fleece. Made from 100% recycled polyester, it’s soft, holds the heat, and has a heathered knit that gives it the textured look of wool. The hood adds another layer of warmth, and laminated pockets give it iconic Covert style.

The Covert Pullover Hoody was previously the Covert Hoody.

Crafted at a Fair Trade Certified facility as part of our commitment to transition 80% of Arc’teryx products to fair trade certification by 2025.

Every kit needs a windshell. It’s essential, packable protection for hikes >and climbs in transitional weather – and often becomes the go-to for any quick trip outside. The Nodin – with its minimalist design and versatile performance – is that shell. The Tyono™ nylon balances wind protection with breathability, and a PFC-free DWR treatment sheds light moisture. It packs into its pocket, and a low-profile StowHood™ adds protection, adjusts with a single pull, and zips into the collar when not in use.

Updated with revised StowHood™ design and PFC-free FC0 DWR treatment.
