eco-friendly is the recycled polyester?","entries":{"45_85_less_energy":"Manufacturing the recycled polyester in this jacket’s stretch wool blend consumes 45–85% less energy than making virgin polyester, according to peer-reviewed lifecycle assessments, so the garment’s fabric-level energy footprint is substantially lower — a concrete, data-backed improvement over a conventional suit jacket.","98_bottle_feedstock":"Roughly 98% of recycled polyester in apparel originates from post-consumer PET bottles, not old textiles, so the recycled content in this jacket almost certainly began as discarded drink containers — a straightforward waste-to-fashion loop that avoids the dead-end downcycling of fabric-to-fabric recycling and gives the jacket a simple, truthful sustainability hook.","comparable_durability":"Recycled polyester fibers retain equivalent tensile strength and abrasion resistance to virgin polyester because the PET polymer structure is identical after processing, so the recycled component in this wool-blend jacket does not compromise the garment’s ability to hold its shape through repeated wear and dry-cleaning — making it as durable as any conventional polyester-wool suit.","30_60_fewer_co_emissions":"Recycled polyester production cuts greenhouse gas emissions by 30–60% versus virgin polyester, so the jacket’s recycled content reduces its carbon footprint at the fiber level — a measurable climate benefit that a buyer can cite when comparing it to a similar jacket made with standard polyester.","indistinguishable_hand_and_drape":"The molecular structure of recycled polyester is identical to virgin polyester once spun into yarn, so the recycled content in this jacket’s stretch
