Alpargali Puffer Jacket

Most puffers rely on loft for warmth. The Alpargali Puffer Jacket takes a different route, according to its maker: a proprietary four-layer insulation system built around aerogel and graphene, which the company says keeps the wearer comfortable even at -40°C.

Aerogel meets graphene

The maker points to aerogel, a material it describes as developed by NASA for space exploration, as the core of the jacket's insulation: very light, yet strongly insulating. Graphene is added, the company says, to spread heat efficiently and evenly so body temperature stays steady across conditions. A 360° torso protection structure is meant to block cold from every side. The aerogel insulation is specified at 1.0mm, which the maker says keeps the jacket light and unrestrictive.

Four layers, nine pockets

• Windproof, waterproof outer layer for sudden rain or snow, per the maker
• Inner layers intended to balance warmth with breathability and move sweat away during activity
• Nine pockets for a phone, wallet, outdoor tools and more
• Eco-friendly materials, according to the campaign

The maker positions the jacket for a broad audience, from city dwellers and outdoor enthusiasts to explorers and professional users, and also claims the technology adapts to warmer climates, not just extreme cold.
