Fabric & Aftercare
Fabric: 100% recycled & recyclable ripstop outer shell, sourced from Japan, bluesign® accredited. C6 (PFC/PFOA/FPOS free) DWR durable water repellent finish. 100% polyamide lightweight lining. PrimaLoft Silver Eco® recycled insulation fill (130g/m²), containing 70% post-consumer recycled content.

Aftercare: We recommend cleaning at 30°C on a gentle machine wash. Cleaning will re-activate the durable water repellent finish on the fabric. When rain ceases to bead on the fabric it's a sign that water repellency is fading and cleaning/re-proofing is required. Return to us for reproofing/repairing when required (charges apply).

The Sastruga takes advantage of synthetic insulation's unparalleled warmth-to-weight ratio to create a warm jacket without being too bulky. The 100% recycled ripstop outer shell is water resistant and windproof, and the concealed ribbed cuffs seal extra warmth in. When space is at a premium the whole jacket can be packed away into the inner pocket, doubling as a handy travel pillow.
i-Spy Traceability Programme - Insulation

Our insulation has a 100% recycled and recyclable ripstop outer shell, and the PrimaLoft® Silver Eco insulation fill uses 70% post-consumer recycled content.

Recycled polyester does not degrade from the recycling process and can be recycled over and over again; plastic bottles and polyester apparel are melted down into pellets and heat-spun into new filament yarn which is then woven into new fabric.

We use a C6 (PFC/PFOA/FPOS free) durable water repellent finish on all of our outerwear.
