Portwest ES1 Essential Softshell 3L

When conditions are unpredictable and you need a jacket that adapts with you, the Portwest ESK50 ES1 Essential Softshell 3L delivers a level of all-round performance that few garments at its price point can match. Windproof, water resistant, breathable, and warm — all wrapped in a clean, professional silhouette that's as at home in a corporate environment as it is on an exposed worksite.

Built from a 94% polyester, 6% elastane shell with a TPU breathable film at 300g, the ESK50's three-layer construction bonds the outer shell, breathable membrane, and micro polar fleece lining into a single, cohesive garment. The result is a jacket that feels substantive and well-insulated without the bulk of a traditional outer layer, while the elastane content delivers a meaningful degree of stretch — allowing a genuine freedom of movement that rigid shells simply can't provide. Whether you're reaching overhead, driving between sites, or working at a desk, the ESK50 moves with you rather than against you.

PFAS-Free Texpel™ Splash Eco — Advanced Water Resistance Without Compromise

The ESK50 is finished with Texpel™ Splash Eco — an extremely water resistant, PFAS-free fabric treatment that causes water to bead and roll cleanly away from the surface rather than soaking through. In an era where sustainability and performance are increasingly expected to go hand in hand, this eco-conscious finish delivers both without compromise. You get outstanding water repellency, and you get it without the environmental concerns associated with traditional PFAS-based DWR treatments.

The ESK50's waterproofing and breathability credentials are independently verifiable: rated to WP 8,000mm for waterproof performance and MVP 3,000g/m²/24hr for moisture vapour permeability — meaning it keeps the rain out while allowing body moisture to escape, keeping you comfortable and dry from both directions.

Windproof and Breathable — Engineered for Real Working Conditions

The durable, windproof, and breathable TPU membrane at the core of the ESK50's 3-layer construction acts as an effective barrier against wind chill — one of the most significant comfort challenges for outdoor workers during the colder months. Combined with the micro polar fleece lining bonded directly to the shell, the ESK50 provides a level of warmth and insulation that makes it a genuinely all-season option, from cool summer evenings through to the depths of autumn and winter.

Corporate Wear and Custom Branding Ready

The ESK50's clean, unbranded design and polished professional aesthetic make it an outstanding choice for corporate wear and custom finishes. The smooth outer surface is ideal for embroidered logos and company branding, making the ESK50 a popular option for businesses looking to create a consistent, high-quality branded outerwear solution for their teams. From client-facing workforces to uniformed site teams, the ESK50 presents exceptionally well and reflects positively on any organisation.

Two Pockets for Everyday Practicality

Completing the package are two secure pockets — positioned for easy access and practical everyday use, whether you're storing a phone, access card, or work essentials throughout the day.
