Lightweight core warmth for active mountain use

The Mountain Equipment Intra Light Women's Vest combines HELIUM 20D fabric, 40g m⁻² Aerius™ synthetic insulation, and an Octayarn Warp-knit back panel to deliver lightweight, breathable insulation for year-round mountain use. Designed for hikers, ski tourers, rock climbers and alpinists, it adds valuable core warmth without unnecessary bulk, working equally well over a base layer or beneath a waterproof shell during demanding mountain days.

Performance & Engineering

• Aerius™ Synthetic Insulation – Engineered with 40g m⁻² Aerius™ synthetic insulation, combining high-resilience hollow fibres and fine-denier fibres to provide excellent warmth-to-weight performance, compressibility and comfort during active mountain pursuits.

• HELIUM 20D Outer Fabric – Built with HELIUM 20D fabric that delivers wind-resistant protection, low weight and exceptional breathability, making it ideal for layering during fast-moving activities in exposed terrain.

• Octayarn Warp-Knit Back Panel – Designed with an Octayarn Warp-knit back panel to enhance moisture transfer and accelerate drying during long approaches, sustained climbs and pack-carrying missions.

• Technical Layering Functionality – Utilises a YKK® Vislon® centre front zip with insulated baffle to minimise cold spots and provide efficient temperature regulation across a wide range of conditions.

• Packable Mountain Utility – Packs into a lightweight stuff sack for compact storage, while two zipped hand pockets and a zipped chest pocket keep essential items secure and accessible on the move.

Care & Longevity

Hand wash or machine wash at 30°C using liquid detergent or a specialist cleaner. Tumble dry on a low heat with a slow spin speed and store in a cool, dry place away from direct sunlight to help maintain insulation loft and fabric performance. Always follow the garment care label and avoid high-heat drying or long-term storage when damp.
