Product Overview
The Stormtech Sierra thermal vest is a sophisticated solution for professionals requiring core warmth without the restriction of a full jacket. Engineered for high performance, this gilet prioritises thermal efficiency through a lightweight design that does not compromise on protection. By utilising Stormtech Thermal Shell insulation and a synthetic down fill, the garment provides consistent heat retention in unpredictable environments. The addition of a Durable Water Repellent (DWR) finish ensures that light rain and moisture do not interrupt your workday, while the windproof outer shell acts as a critical barrier against the elements.
Key Features
Stormtech Thermal Shell Insulation: The advanced synthetic down fill provides high-level core warmth while remaining impressively lightweight for all-day comfort.
Durable Water Repellent (DWR) Finish: This technical coating encourages water to bead off the fabric surface, keeping you dry during brief showers.
Windproof Outer Shell: The high-performance exterior blocks wind chill, ensuring your body temperature remains stable in exposed conditions.
Internal Full-Length Storm Flap: Designed to prevent drafts from penetrating the zip, providing an extra layer of thermal security.
Zipped Handwarmer Pockets: These offer a secure space for essential items and a practical way to keep hands warm during stationary tasks.
Adjustable Hem: Allows for a tailored fit that seals in heat and prevents cold air from entering from below.
Design & Performance
Constructed from 100% polyester pongee with a matching polyester lining, the Sierra vest is designed for longevity and resilience. The pongee weave provides a smooth, durable finish that resists snagging, making it suitable for active work environments. Despite its lightweight feel, the synthetic down fill is highly effective at trapping air to maintain warmth, mimicking the properties of natural down while performing better in damp conditions. The garment is designed to be low-bulk, allowing for a full range of motion whether you are operating machinery or driving between sites.
Customisation: Print & Embroidery
This thermal vest is an excellent canvas for corporate branding, featuring specific decoration access to ensure a superior finish. For a traditional, professional appearance, we recommend embroidery. Our Telford-based team can expertly stitch your company logo or staff names onto the chest, creating a high-quality look that lasts. If you require larger, more vibrant graphics, our print services are ideal for ensuring your brand is visible from a distance. With MyWorkwear’s expertise dating back to 1976, we ensure every logo is applied with precision, maintaining the integrity of the garment's technical fabrics.
Use Cases
The Sierra thermal vest is perfectly suited for site managers, surveyors, and delivery drivers who frequently move between indoor and outdoor environments. Its lightweight nature makes it an ideal layering piece over a sweatshirt or under a larger waterproof coat in extreme weather. It is also a popular choice for corporate uniforms where a professional, uniform appearance is required for staff working in cooler warehouses or during outdoor events.

Practical Advice
When selecting your size, consider what you intend to wear beneath the vest. For those who prefer heavy knitwear or thick sweatshirts, you may find the more generous end of our size range (S to 5XL) accommodates layering more comfortably. The adjustable hem is particularly useful for fine-tuning the fit once your layers are in place.
Caring for your product
To maintain the high-performance characteristics of the Stormtech Thermal Shell and the DWR finish, proper maintenance is essential. We recommend a cold machine wash on a gentle cycle with similar colours. Using cold water prevents the synthetic fibres from breaking down prematurely, ensuring the vest retains its shape and insulating properties.
It is vital to avoid the use of fabric softeners and bleach. Softeners can clog the technical pores of the fabric and strip away the water-repellent coating, while bleach will damage the polyester structure and lead to discolouration. To dry the garment, hang it in a well-ventilated area. Avoiding the tumble dryer prevents heat damage to the synthetic down fill, keeping it lofty and effective.
Do not iron the vest or its decoration. High temperatures from an iron can melt the polyester pongee and permanently damage your embroidered or printed logos. Similarly, dry cleaning is not recommended as the harsh chemicals can degrade the technical shell and insulation.
