Sustainability through Science
We believe in using science to create a product that solves not only the challenges of our daily lives, but also is a lower-impact alternative to other options. We're engineers, and all of our materials and manufacturing are rigorously analyzed to minimize our footprint, backed by data.
Zero Emissions & Climate Neutral Certified
Apparel production accounts for 8% of global carbon emissions. We are Climate Neutral Certified, meaning we have measured, reduced, offset and certified our entire carbon footprint. Reductions include solar-powered mills, recycled materials and maximizing sea-freight shipping. We undergo a rigorous analysis of the lifecycle of our products and operations, and it guides how we design our products.
Typical apparel production wastes 35% of the material. Since 2015 we’ve pioneered 3D Print-Knit production, an on-demand, zero waste production technique that accounted for 26% of production in 2020.
Carbon Capture Renewable Fibers
Fossil-fuel based fibers increase carbon in our system. We’ve developed corn-based polyester fibers (Kinetic) and wood-based fibers from FSC Certified forests (Fusion) with our partners that capture carbon in bio-based fabrics.
Virgin Polyester generates over 2x the carbon emissions than Recycled Polyester. Recycled Polyester reduces carbon emissions by 52% for fibers. That’s why 3/4 of our products that use synthetic fibers contain over 50% recycled materials. Our goal is 100% like our Aero Zero, Responsive and Mercury Jacket.
Extending product life cycles to reduce emissions and material waste. All of our products undergo rigorous ASTM and AATCC fabric and garment testing for abrasion, pilling, shrinkage, colorfastness, seam strength and wash cycling to ensure they exceed the industry standard 2.5 rating with a 3.5 or above.
Garments get retired before the end of their useful life. Since 2014, we’ve run our 1 In, 1 Out Program to collect gently used professional clothing (even those that aren’t ours), and have facilitated donations to career-readiness programs where the garments can continue to serve others.
PFOA-Free Durable Water Repellent
The industry standard C8-fluorinated water repellents have been found to have an effect on the human endocrine system. Long-chain C8 PFC’s can wash off of garments and persist in our water supply. We have switched completely to short-chain C6 and PFC-free durable water repellent that achieves an 80% performance rating fter 20 washes. Learn more through our Care Program.
Factory Selection & Certification
Certified facilities are critical to safe and fair working conditions while maintaining quality. Our factories are certified through WRAP (Worldwide Responsible Accredited Production), BSCI (Business Social Compliance Initiative), and we visit all of them personally.
Synthetic garments and fleeces in particular emit microfibers during wash cycles, and have. Our fabrics are designed to be machine washed cold and tumble dried on low. Washing on the gentle cycle will further reduce agitation of the fabric. You can also use a Guppyfriend bag to help further filter out microfibers. Using a front-load washer has 1/7th the fiber loss of a top loader. Learn more through our Care Program.
BlueSign / Environmental Certifications
Fabric production is resource-intensive with significant byproducts. Our fabric mills have environmentally-responsible production certifications through BlueSign and/or Oeko-Tex 100 (Human-health certification for fabrics).
To reduce the amount of water needed to dye our products, we focus on the pressure and temperature of boiling—turning the solvent from a liquid to gas, while leaving the dye behind. By using pressurized carbon dioxide instead of water as our solvent in the dyeing process, and releasing it as a gas, we lower our energy use considerably and save over 130,000 of gallons of water every year.
Infinity - Circular Production
Our shirts are built and tested to last, but when you're ready to retire your Aero Zeroº we can give them a new life. Working with our partners at Shinkong Textiles, we've developed a revolutionary hybrid mechanical-and-chemical recycling process that can separate polyester fibers. We then re-spin it back into yarn that's just as strong, durable and soft as before, creating the world's first circular dress shirt.
Biodegradable / Recyclable Packaging
E-commerce packaging is critical to ensure safe product delivery, but can lead to waste. We use shipping boxes and mailers made of 100% recycled paper cardboard, as well as compostable poly bags - allowing all of our packaging to be recyclable or biodegradable.
Fast-fashion with seasonal colors, patterns and silhouettes lead to premature retirement of useful clothing. Our garments are built around time-tested and timeless silhouettes in versatile, neutral color pallets. You won’t find wild colors here, but what you will find is long-lasting, easy to coordinate products that will be in style longer.
Lower carbon footprints by giving products a new life. Our certified pre-owned inventory allows you access to gently worn garments, at a low price and lower carbon footprint.
