Eco insulating jacket in the mountains

The best insulating jacket doesn't cost the earth

By Kenny Stocker

The great reviews of our winter products continue to pour in, and today it is the turn of our Heiko Primaloft insulated jacket. As winter creeps up on us, top outdoor mag Live for the Outdoors have chosen a good time to drop their Best synthetic insulated jackets 2023 for hills and mountains review. We were chuffed to see it included our Heiko Primaloft jacket scooping up the Best Value in Test award by gear editor Chris.

As awareness and concern about the environmental impacts of outdoor gear grows, there has been a rise in the popularity of synthetic insulation. The Heiko is presented as a prime example of this trend, leading Chris to repeat our design team's claim that it is Alpkit’s most sustainable jacket to date.

Chris applauds the Heiko minimalist design – almost everything, aside from the zips, is made from 100% recycled polyester. This includes the Primaloft Silver Eco filling, which the review praises for its impressive warmth and lightweight properties. With a density of 60gsm, it provides year-round warmth without the bulk.

Weighing in at just 344g for a men’s medium, the Heiko is celebrated for its lightweight feel. Chris captures this perfectly, saying it’s the kind of jacket that you can forget you’re wearing. But it’s not just about being lightweight; the jacket also scores points for comfort, described as soft and almost silky, adding to the overall comfort of wearing it.

When it comes to weather protection, the Heiko’s got you covered. Both the inner and outer layers are made from 100% polyester, with the outer layer treated with a PFC-free DWR for water repellency. The jacket's thin design also makes it perfect for layering under a waterproof shell.

In summary, the Heiko Synthetic Jacket gets a big thumbs up in this review. From its sustainable materials and lightweight feel to its comfort and practical design, it’s clear the Heiko meets the needs of modern hikers, bikepackers and climbers. So, if you're looking for a new synthetic jacket, the Heiko is definitely worth checking out.
