Engineered for Performance

The Womens Sierra Down Jacket represents the pinnacle of corporate outerwear engineering, specifically designed for businesses that refuse to compromise on quality or thermal efficiency. At the core of this garment is its 700 fill power insulation, derived from a premium 90/10 duck down and feather blend. In technical terms, this high fill power rating indicates an exceptional warmth-to-weight ratio, trapping significant amounts of body heat within the loft structures without adding the heavy bulk typically associated with synthetic alternatives. This makes it far superior to standard fleeces for outdoor corporate events or commute-heavy roles. The outer shell is constructed from a lightweight yet durable 100% Nylon fabric, treated with Bionic Finish ECO. This advanced, ecological hydrophobic coating ensures that the jacket sheds light rain and snow effectively, maintaining the loft and insulation properties of the down even in damp British conditions. The inclusion of YKK Metalux zips adds a final layer of mechanical reliability, ensuring that the fastening systems withstand daily use without failure.

Comfort & Workforce Utility

Designed with the modern female professional in mind, the Sierra jacket offers a tailored silhouette that enhances corporate identity while providing unrestricted movement. The lightweight 35gsm shell ensures that the wearer does not feel weighed down, reducing fatigue during long shifts or extensive travel. The channel construction is not merely aesthetic; it is engineered to hold the down in place, preventing cold spots and ensuring consistent thermal regulation across the torso. For staff who spend time driving or commuting, the jacket's compressibility is a key asset, allowing it to be worn comfortably in vehicles or packed away easily when transitioning indoors. The side pockets are discreetly integrated with hidden zips, providing secure storage for company phones, keys, or access cards without disrupting the clean lines of the uniform. The high collar offers additional wind protection for the neck, eliminating the need for additional accessories in mild winter weather.

This garment is optimised for premium customisation. The smooth nylon surface provides an excellent substrate for embroidery, ensuring your logo sits flat and crisp against the fabric. We recommend subtle chest positioning to maintain the jacket's high-end aesthetic. To create a cohesive winter uniform, complete the uniform with Trousers from our formal workwear range.
