What is the Alpine 850 Nano Hoodie?
It's an ultra-light down jacket that uses 850FP ExpeDRY™ goose down to provide an exceptional warmth-to-weight ratio. With an uncompromising focus on thermal efficiency, the Alpine 850 Nano excels in the coldest environments and fast and light adventures where every gram counts. It's ideal to be worn as a super warm midlayer or lighter outer layer when ski touring, mountaineering and tacking alpine missions.
What is it made from?
The Alpine 850 Nano is constructed from ultralight 10D Pertex® Quantum and is predominantly filled with ExpeDRY™ 90/10 goose down insulation, with PrimaLoft Gold panels in high moisture areas.
Insulation: Montane has used 100g of ExpeDRY™ 90/10 goose down for an exceptional warmth-to-weight ratio. The goose down has a fill power of 850 and is RDS and Track my Down™ certified, reassuring you that it has come from responsible, ethical sources.
ExpeDRY™ by Allied Feather is an innovative, chemical-free, non-toxic alternative to hydrophobic-treated down. ExpeDRY™ uses chemical-free gases to permanently bond non-toxic gold particles to the individual down clusters, aiding the evaporation of water molecules, causing the down to dry faster and stay dry in high humidity and extreme conditions. This highly effective ability to move moisture helps the down retain maximum loft (fluffiness) and deal with various sources of moisture such as rain, snow and sweat, making it ideal for various environments and activities.
Montane has strategically placed PrimaLoft Gold synthetic insulation panels on the underarm gusset and front collar for enhanced durability, warmth, and moisture management. PrimaLoft® Gold Insulation is breathable, warm and highly efficient, with a lower bulk and weight than most synthetic insulation. It uses small fibres thinner than human hair to provide maximum thermal efficiency; the thinner the fibres, the warmer the insulation will be. Synthetic insulation is also effective when wet, making it a robust choice for high-moisture areas around the face and the underarms.
Can't quite catch the lingo? Here's a quick breakdown.
Fill power - Fill power measures the warmth and efficiency of the down, alongside its ability to loft/fluff up. A rating of 850 fill power means that 1oz of this down fills 850 cubic inches of space when fully lofted.
RDS - The Responsible Down Standard ensures that the down is sourced from happy birds who haven't been plucked and have been well cared for.
Track My Down - Track My Down is a portal that can be accessed through SourceTRACK™ to learn about the fill used in your individual jacket. It allows you to find the source region of the down, verified third-party tested final fill power, cleanliness, content analysis and links to reports and certificates. To access this information, you will find a SourceTRACK™ lot number printed on the garment's hang tag, which you can enter into the Track My Down website.
Hydrophobic - Hydrophobic down dries out and lofts quicker, resisting moisture from light rain or sweat and condensation that may build up inside the jacket during intense mountain activity. PFC-free Hydrophobic finishes like HyperDRY™ are not fluorinated and therefore don't cause damage to the environment like previously used fluorinated treatments.
Outer and lining: The Alpine 850 Nano's outer shell and lining are constructed with a durable and lightweight recycled 10D Pertex® Quantum with a PFC-free DWR (durable water repellent).
Pertex® Quantum provides a lightweight, soft feel and helps improve the efficiency of the insulation by trapping still air. It's 100% recycled yet still has a fantastic level of performance, providing effective windproof protection and optimised heat retention.
The ultralight Pertex® Quantum fabrics gently encase the down insulation, showing off natural 'blemishes' in the down that are sometimes visible through the jacket. These 'blemishes' are a great sign that the goose down used is of the utmost highest quality.
The outer and lining are finished with a PFC-free DWR coating (durable water repellent), which encourages light rain or snow to bead off the fabric. Just like the Hydrophobic treatment, PFC-free DWR (C0) is much more responsible than regular water-repellent treatments, as it doesn't use harmful forever chemicals that cause damage to the environment and ecosystems.
What are its features?
The Alpine 850 Nano feature set is reserved for the essentials only; the whole jacket is critically engineered for maximum performance and minimal weight.
An insulated hood provides warmth and protection from the elements. The hood features elasticated micro-binding around the edge to provide a snug, secure fit around the head, optimising thermal efficiency and comfort when underneath a climbing helmet. The jacket is fastened with a simple central zip that is lightweight to help keep overall bulk to a minimum.
The Alpine 850 Nano seams have been strategically placed throughout the jacket to minimise vertical seams, optimise fabric usability, lower bulk, and reduce cold spots, with the bonus of creating a clean and timeless aesthetic. The jacket uses synthetically insulated panels across the front of the face and the underarms for better moisture management and durability in high-wear, high-moisture areas.
For storage, you'll find two hand pockets with lightweight YKK zippers that offer space for a mobile phone, trail snacks and energy gels to keep you fueled during your adventure.
Finally, elasticated cuffs and a micro elasticated hem help seal in warmth and keep cold weather out of the jacket.
