An idea for cold weather clothing that replaces traditional insulation with air. The inflatable insulation has been repackaged into a simpler form and uses a simple hand pump to adjust your core warmth. The jacket was designed to offer some clear benefits over traditional fill insulation materials like goose down and Primaloft. It offers the wearer the ability to adjust the garment's warmth level throughout the day, adding versatility without too much emphasis on layering. Fabric material is an ultra-high molecular weight polyethylene that combines extreme strength with very low weight. The highly-waterproof material is tear-resistant, resistant to folding and stretching, UV- and chemical-resistant. The lightweight system also made for highly-packable garments – instead of a big, puffy jacket, you could slide a deflated shell into your backpack or suitcase.
