Description summary

Conquer extreme cold with the ultralight MONTANE Apex 900 Hoodie. Engineered for best-in-class warmth-to-weight performance, this packable down jacket features 900+ fill power ExpeDRY™ Goose Down and 10D recycled PERTEX® Quantum fabric. Its windproof, water-repellent shell, stitch-through baffles, and Reach+ articulation ensure maximum thermal efficiency and unrestricted movement. The helmet-compatible hood and 2-way zip provide essential protection, while internal pockets and a stuff sack offer convenience. Lightweight and durable, it´s your ultimate companion for high-altitude adventures

Engineered for ultralight thermal efficiency, the Apex 900 Hoodie offers best in class warmth to weight performance for high altitude mountaineering.

It’s an extremely warm, packable and lightweight down hoodie. The 900+ fill power ExpeDRY Goose down, ultralight 10D PERTEX® Quantum fabric and the expertly designed feature set combines to give you maximum function and performance for the most extreme conditions.

Pertex® Quantum:
- Windproof, soft to the touch and 100% recycled. PERTEX® QUANTUM is constructed in a tightly woven structure to provide windproof protection and trap still air inside the jacket. This allows the down insulation to fully loft and retain its warmth. The fabric is lightweight, packable and soft to the touch. Finished with a non-fluorocarbon water repellent which allows the fabric to shed light rain and snow, allowing the jacket to provide weather protection in adverse conditions. The fabric is constructed using highly abrasion resistant nylon ripstop, incorporating reinforcement yarns to provide durable resistance to tearing, helping the fabric to withstand harsh mountain environments.

Expedry™ Goose Down. Fast-Drying Real-Gold Tech.:
- The Apex 900 is filled with ExpeDRY™ Goose Down, which has non-toxic gold particles bonded to it for fast-drying performance and industry-leading warmth. The chemical-free technology works because gold particles vibrate water molecules, just like heat does, to speed up evaporation to a rate faster than the water absorption rate of down, while managing moisture from the body.

Features:

- Pertex® Quantum: 10D Super lightweight recycled nylon nano ripstop with a non-fluorocarbon water repellent finish
- ExpeDRY goose down: 90/10 ExpeDRY goose down at 900+ fill power
- Adjustable Hood & Hem: Self sealing cuffs and hood aperture to lock in warmth
- Stitch-Through Baffle: Minimal stitch-through baffle construction for a lightweight, packable build
- Reach + construction: Offers unparalleled arm lift and articulation for excellent movement
- Helmet Compatible Hood: Lycra bound hood with rear crown adjustment
- 2-Way Zip: 2-way lightweight YKK Vislon Natulon® recycled front zip
- Internal Pockets: Internal stash pockets
- Cube Stuff Sack: Includes Cube stuff sack for efficient packability. Constructed to provide maximum fabric for use for garment repair.

Specifications:

- Weight: 380 g
- Outer: 100% Nylon (recycled)
- Insulation: Contains non-textile parts of animal origin (90/10 goose down)
