FAQs
What is the primary difference between down and synthetic insulation in this jacket?
The jacket uses high-loft 900FP down in the core areas for maximum warmth-to-weight efficiency, while PrimaLoft Gold synthetic insulation is used on the sides, cuffs, shoulders, and hood base. Synthetic insulation is more resilient to moisture and retains insulating properties when damp, making it ideal for high-sweat areas.
Is this jacket waterproof?
No, the jacket features a Pertex Quantum exterior which is water-resistant and windproof, designed to repel light rain and snow. It is not a substitute for a waterproof shell in heavy precipitation.
How do I properly care for the down insulation?
It's crucial to wash with a specific down wash and tumble dry on low heat with dryer balls to maintain the down's loft and warmth. Avoid regular detergents and fabric softeners, which can degrade the down.
Can I wear this jacket over a thick fleece?
The jacket has a slim, articulated fit designed for mobility and layering under a shell. While it can fit over a lightweight fleece or base layer, a very thick fleece may restrict movement or create an uncomfortable fit.
What activities is this jacket best suited for?
It is best suited for high-output mountain activities such as alpinism, ski touring, mixed climbing, and fast-and-light winter expeditions where weight and packability are critical, and warmth is essential.
What does 'body-mapped insulation' mean?
Body-mapped insulation means the type and amount of insulation are strategically placed in different areas of the jacket based on the body's thermal needs and moisture-generating zones. This optimizes warmth, breathability, and comfort.
How durable is the Pertex Quantum exterior?
Pertex Quantum is known for its excellent strength-to-weight ratio, providing good durability and abrasion resistance for its lightness. It's robust enough for general mountain use but should be treated with care to avoid significant snags.
Troubleshooting
Jacket feels less warm than expected.
Ensure the down insulation has been fully re-fluffed after washing and drying. Check that all zippers are fully closed to prevent drafts. Consider if significant moisture has compromised the down's loft.
Jacket doesn't pack down as small as before.
The down may be clumping due to moisture or compression. Try a thorough drying cycle with dryer balls to restore loft. Ensure the jacket is completely dry before attempting to pack it.
Zipper is stiff or difficult to use.
Gently clean the zipper teeth with a soft brush and a small amount of water. Apply a silicone-based zipper lubricant sparingly. Avoid forcing the zipper.
Minor fabric abrasion or tear.
Use a specialized fabric repair patch or tape designed for technical outdoor gear. Clean the area thoroughly before application for best adhesion.

Care Instructions:
- Washing: Machine wash on a gentle cycle with a technical down wash detergent. Do not use fabric softener or bleach. Close all zips before washing.
- Drying: Tumble dry on a low heat setting with clean tennis balls or dryer balls to help restore loft to the down. This may take several cycles.
- Storage: Store in a cool, dry place, preferably in a breathable bag, not compressed long-term. Avoid storing in damp conditions.
- Repairs: For small tears, use a seam sealer or repair tape designed for technical outerwear. Consult a professional for larger damages.
