Heiko
$189.99
With Primaloft Silver-eco warm, Heiko punches well above its weight on breezy belays, showery summit stops and chilly evenings around the tent. Windproof, water resistant and highly compressible, Heiko packs down into its own pocket.
- Excellent Primaloft warmth and fully windproof
- Highly compressible, fitting into its own chest pocket
- Uncompromising performance made from 100% recycled fabric and insulation with environmentally friendly water-resistant treatment
- Versatile jacket and mid-layering piece
The Heiko's outer fabric and inner liner are made from a super light and soft recycled polyester fabric. This 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® is water resistant too, repelling water and keeping its insulating ability even when wet. Combined with the fast-drying fabric (treated with a PFC-free DWR), this makes the Heiko ideal for changeable conditions — every other day in the British Isles, then!
Not just a versatile outer jacket, the Heiko can also double up as a super warm midlayer in colder temperatures. Its hoodless design and low-profile 60gsm insulation fit 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. And it's not just any recycled polyester fabric. It's a fabric that feels amazing next to the skin. We've even used it as the lining in our sleeping bags!"
