Slim Fit
Slim, athletic cut through the body for a low-bulk layer that fits cleanly under a shell or wears solo on cold alpine starts
Lightweight Performance
Purpose-built for lightweight performance where every gram counts, from ski touring to alpine ascents
Hybrid Construction
Hybrid build pairs an insulated body with non-insulated, stretch-woven hood, sleeves, and side panels for full range of motion
800-Fill ProDown™
800-fill ProDown™ is natural down insulation enhanced with a hydrophobic finish that allows it to dry faster than untreated down after moisture exposure
Pertex® Y Fuse Body
Pertex® Y Fuse fabric on the main body increases downproof and water-beading properties, keeping insulation lofted and drier
Non-PFC DWR Finish
Non-PFC durable water-repellent finish on both the body and stretch panels sheds light precipitation without PFCs
Recycled Nylon Throughout
Body fabric made with 100% recycled nylon; hood, sleeve, and side-panel fabric made with 88% recycled nylon for lower-impact construction
Low-Profile Hood
Low-profile hood with a pre-tensioned elastic opening delivers a secure fit under a helmet or beanie without flapping in the wind
Insulated CF Zip
Exposed #3 YKK® VISLON® center front zip paired with an insulated internal draft flap to seal out wind at the chest
Mobility Sleeves
Raglan sleeves and underarm gussets allow full arms-up mobility for climbing, reaching, and high-stepping on technical terrain
Chest Pocket & Internal Pouch
Chest pocket with an exposed water-resistant reverse-coil zip plus an internal mesh pouch sized for skins, gloves, or small essentials
Hand Pockets
Hand pockets with exposed water-resistant reverse-coil zips keep hands warm and small items secure against the elements
Stowable
Packs into its own left hand pocket for compact stowage in a pack or harness when the layer isn't needed
Thumb-Loop Cuffs
Flat-sewn elastic cuffs with integrated thumb loops keep sleeves anchored over hands and seal in warmth without bulk

Certification

Washing
Machine wash cold on a gentle cycle with a down-specific cleaner. Close all zippers and turn the hoodie inside out to protect the Pertex® shell, stretch panels, and bonded seams.
Drying
Tumble dry on low heat with two clean tennis balls or dryer balls to break up down clumps and restore full loft. The stretch panels dry quickly; the insulated body may take 2–3 cycles to dry fully.
DWR Refresh
Refresh the non-PFC DWR finish on both the Pertex® body and the nylon/elastane stretch panels periodically with a spray-on or wash-in DWR treatment to maintain water-beading performance.
Storage
Store uncompressed on a wide hanger in a cool, dry place. Avoid long-term compression in a stuff sack, which can damage ProDown™ loft and crease the stretch panels over time.
Repairs
Small tears in the recycled nylon ripstop or stretch panels can be patched with tenacious tape or sent to a TNF repair center. Address damage early so insulation doesn't escape.
