What insulation is used in the Lightline Men's Jacket?
The jacket uses 296 g of duck down in size L, with a minimum 90/10 down-to-feather content and 700 fill power. Mountain Equipment says the fill is sourced through its DOWN CODEX programme and the Responsible Down Standard; each product also carries a code for tracing the down batch and its stated content.
How should the Lightline Men's Jacket be washed and dried?
Wash it only when necessary, using a specialist down-cleaning product rather than detergent or fabric softener. Mountain Equipment recommends a low- to medium-spin 30°C cycle, thorough rinsing at least twice, and careful handling while wet. Dry it extremely thoroughly at the lowest tumble-dryer heat, checking periodically; drying can take several hours. Do not dry-clean it.
How should I store the Lightline between uses?
Air the jacket during use when practical and dry it thoroughly before storage. When it is not being worn, store it uncompressed—hung in a wardrobe or loosely placed in a large storage sack or pillowcase. Avoid leaving it in its lightweight stuff sack or a pack pocket for long periods, because prolonged compression is not the recommended storage method.
What weather protection does the Lightline provide?
The jacket has a 40D Drilite Loft outer fabric described by Mountain Equipment as windproof and highly weather-resistant, with a PFAS-free durable water-repellent finish. The product page positions it for protection from melting snow and spindrift, but describes the shell as water-resistant rather than waterproof. A 20-denier downproof lining is used inside.
What warranty and repair support applies to this jacket?
Mountain Equipment's guarantee covers the original purchaser against defects in components, materials, and workmanship for the product's reasonable life, with repair or replacement at the company's discretion. It excludes normal wear, accidents, and inappropriate use, and requires proof of purchase. The brand's care guide also describes professional repairs for issues such as damaged zips, drawcords, fabric tears, and baffles.
Is the Lightline's hood removable and suitable for layering?
Yes. The product has a zip-off Mountain Insulated Hood with a wired peak, three down panels, and adjustable drawcords; removing it leaves a high collar. Mountain Equipment says the fit is designed for wearing over base and mid-layers, while the hem drawcord and adjustable cuffs help seal out cold and refine the fit.
