What is the Sirocco XT Hoodie?
The Sirocco XT Hoodie is designed for those days when you're working hard in the cold and don't want your insulation holding you back.
Lightweight and warm, it's built for highly breathable active insulation, to keep you feeling protected and comfortable throughout the day, whether hiking, hill walking, climbing or tackling more technical ascents.
Materials & Technology
PrimaLoft® Gold Active Vent Insulation
The Sirocco XT uses PrimaLoft® Gold Active Vent insulation in a body-mapped construction for breathable warmth, with highly effective moisture management to keep you comfortable when the trail gets tough.
Primaloft® Gold Active is a synthetic insulation that provides ample warmth, even when wet. The ability to retain heat when wet is a huge advantage of synthetic insulation compared to down, alongside being a vegan alternative.
This insulation is also incredibly air permeable for excellent levels of breathability to help regulate body temperature and reduce the risk of overheating during climbs or fast-paced movement.
It's made from 80% recycled polyester, which, though recycled, maintains performance and feel. This insulation does not migrate and has a four-way stretch to enhance flexibility and freedom of movement, whilst also being compressible and quick-drying, making it well-suited to the unpredictable UK mountain conditions.
Body-Mapped Insulation Design
Montane has used a body-mapped insulation construction, placing 80g insulation in the core for warmth and 60g insulation in higher-movement areas such as the arms and hood. This combination of insulation provides warmth in key areas, whilst keeping bulk to a minimum in others for maximum mobility and comfort. It also helps keep the jacket's weight and packsize to a mimimum, allowing it to take up less space in your pack.
FEATHERLITE™ Air Fabric
The outer and lining of the jacket are constructed with Montane's 20D Featherlite Air material, which is entirely made from recycled nylon. Featherlite Air is a tightly woven, lightweight and durable ripstop material engineered to provide wind resistance with exceptional breathability for high-output activities. The fabric features a mechanical stretch that allows the material to move with you, instead of holding you back.
Fluorocarbon-Free DWR Finish
The outer of the jacket is finished with a non-fluorocarbon DWR (durable water repellent) coating to provide light water resistance for added protection in changeable weather conditions. However, please note that this does not make the jacket waterproof - we always recommend carrying a waterproof shell for wet conditions.
Features and Functionality
Breathable Insulated Construction
The Sirocco XT Hoodie uses a combination of an air-permeable, yet highly wind-resistant outer and breathable insulation to allow the jacket to efficiently regulate body temperature. This clever construction helps keep you feeling comfortable throughout the day, preventing you from overheating on tougher sections of trail, while still providing ample warmth in cold conditions.
Lightweight Mountain Hood
A close-fitting hood provides additional warmth and protection without adding unnecessary bulk, allowing you to comfortably wear it underneath a climbing helmet or waterproof shell for maximum protection. A single-point rear adjustment allows you to fine-tune the fit to ensure it stays in place and moves with your head for maximum field of vision.
Pack and Harness Compatible Storage
For storage, you'll find two zipped hand pockets and an external chest pocket for keeping essentials close to hand. The pockets are positioned to remain accessible when wearing a climbing harness or backpack hip belt, ensuring they stay functional, whatever the adventure.
Recycled YKK NATULON® Zips
The jacket is fastened with a YKK NATULON® recycled front zip that provides reliable performance while reducing environmental impact. The full-length zip allows quick ventilation to help regulate temperature, should you start to warm up on steep ascents.
Stretch Construction for Freedom of Movement
The jacket features a mechanical stretch in the fabric and insulation to allow unrestricted movement during climbing, scrambling and hiking with poles. Low-profile seams throughout help reduce bulk and improve comfort level when wearing a backpack for long periods.
