Warm, windproof and packing down into its own pocket, the Heiko punches well above its weight on breezy autumn belays, spring summit stops and chilly summer evenings around the tent.
- Excellent warmth to weight ratio and fully windproof
- Super compressible, fitting into its own chest pocket
- 100% recycled fabric and 100% recycled insulation
When space is limited and the weather forecast’s about as effective as the Ben Nevis Forecasting Stone, it’s hard to know what layers to pack. The Heiko is versatile in a range of conditions and packs in a surprising amount of warmth for its weight and pack-size.
..Read moreThe outer fabric and inner liner are made from a super light and tough recycled nylon fabric. The dense weave of the fabric forms a fully windproof sandwich around the insulation (inedible though), trapping vital body heat when you stop moving or the wind picks up.
We've used PrimaLoft® Silver Eco, a 100% recycled insulation, for its excellent warmth to weight ratio. This highly compressible fill allows the Heiko to pack away into its own chest pocket (complete with hang loop for clipping to climbing harnesses).
PrimaLoft® insulation doesn’t absorb water either, keeping its insulating structure even when wet. This, combined with a fast-drying and PFC-free water-repellent treated outer fabric, means the Heiko really excels in changeable conditions — every other day in the British Isles, then!
Not just a versatile outer jacket, the hood-less, low-profile design means the Heiko can also double up as a super warm mid-layer in colder temperatures, its quilted 60gsm insulation fitting neatly under outer shells.
Designer's Notes
"With a PFC-free DWR and 100% recycled fabric and fill, the Heiko is our most sustainable jacket yet. We could have used (readily available) recycled polyester for the inner and outer fabrics, but we worked really hard to find a recycled nylon that would make the jacket last longer and further add to its sustainable design."

Product Care Information
Caring For Your DWR
To keep your jacket’s durable water repellent (DWR) treatment in tip-top condition, wash it regularly in pure soap or a specialist cleaner (like Nikwax Tech Wash or Grangers Performance Wash). You may also need to refresh the treatment about once or twice a year (depending on usage) using a reproofer. Using a spray-on reproofer preserves your jacket's wicking ability.
Washing Instructions
Wash on a delicate cycle at 30˚C or hand wash with lukewarm water. Use a technical wash product or pure soap. DO NOT use detergent, fabric conditioners or softeners. Rinse thoroughly in clean water. Line dry or tumble dry on low heat. Use a cool iron to reactivate the DWR.
Environmental considerations
Recyced Fabrics
The Heiko's inner and outer fabrics are 100% recycled nylon, made from post-industrial recycled content. This uses up leftover matter from nylon production as well as fabric scraps from the cutting process to remake it into brand new nylon fabric!
Recycled Insulation
We’ve used also used PrimaLoft® Silver Eco, a 100% recycled polyester insulation, for the fill.
