Responsibly sourced cashmere relies on meticulous record-keeping and full transparency from farm to finished garment. White + Warren is proud to offer the finest quality cashmere that has been controlled at every point in the manufacturing stage. All of our 100% cashmere styles are made entirely from fiber traceable to regions of Inner Mongolia and will always be produced with transparent ethical and environmental practices. We have been working with the same factory since the beginning, and as of 2021, our factory has received two important certifications that are necessary to provide traceable cashmere: The Good Cashmere Standard® and The Sustainability Fibre Alliance. For more information, check out our blog post on Responsibly Sourced Cashmere.
Cashmere that meets the Global Recycle Standard (GRS) crafted from pre-consumer cashmere yarns. Recycled cashmere was first introduced into our fabric list with the Holiday 2017 collection. The yarn comes from a family-owned mill in Tuscany, which takes sweaters that would otherwise go to waste, shreds them back into fiber form, and spins them into renewed yarn. White + Warren was the first U.S. brand to use this yarn from the Italian mill. For a behind-the-scenes look at how our recycled cashmere is made, visit our blog.
A natural fiber from the fast-growing flax plant, linen requires fewer resources than other natural fibers (like cotton), including water. Luxurious and lightweight, linen gets softer with each wear. White + Warren also offers styles in a fabrication we call “linen gauze,” which is a blend of linen, Better Cotton Initiative (BCI) certified cotton, and recycled nylon CiCLO®.
A blend of cotton, spandex, and modal from Peru. Thanks to the touch of spandex, our Peruvian Cotton Modal tees never lose their shape, creating an extended shelf-life that’s similarly more sustainable. Our Peruvian Cotton Modal is dyed in our factory’s dyeing house, which is committed to the reduction of chemicals in the dyeing process. For example, the dyeing house uses a post-dye water treatment that reduces the percentage of contaminants in the water.
Our Italian Blend Crochet styles are made from a blend of cotton and polyester crafted from recycled plastic bottles harvested from the ocean floor. At White + Warren, each recycled bottle cotton sweater represents two bottles that have been repurposed. We partner with a skilled Italian mill that processes them into a yarn that’s soft and luxurious.
Our sustainable cotton, sustainable cotton blend, cotton cashmere, linen silk marl, and linen gauze yarns are dyed, spun, and engineered with the environment in mind, ensuring there are no harmful chemicals used in the production process and no pollution leaked into the water or air. Our dyes are certified by industry-wide standards, including OEKO-TEX®, Intertek, and Reach Compliance. Our dyes have a high absorbency, and its effectiveness directly leads to less water and energy consumption. Additionally, 60% of the water used at our factory’s dye houses are recycled back into the production process through a high-powered wastewater treatment plant. All chemicals used meet strict toxicity and biodegradability criteria.
One of the more sustainable aspects of cashmere is that it is easy to dye compared to other yarns and fabrics. For example, polyester must be dyed through a complex solution, as it is a hydrophobic material that repels liquid. Cashmere, on the other hand, can be dyed in a simple water dye bath, since it is naturally hydrophilic, meaning it easily absorbs liquids. At White + Warren, we also incorporate water conservative dyeing methods for linen, which uses a natural wash, in most colors, that requires less water than traditional dyeing.
Our sustainable styles are only as good as the packaging we deliver them in. White + Warren is committed to reducing its environmental footprint through the use of compostable packing materials, recycled hang tags, and more.
Our poly bags are made with EPI (Environmental Products Inc.) biodegradable plastic; EPI is the proponent and leader of oxo-biodegradable plastic additive technology. The poly bags are also made with TDPA™ technology and therefore, are oxo-biodegradable. Trade regulations require that every item be packed in a bag, but choosing to use these bags instead of conventional plastic minimizes the negative impacts associated with standard plastic. Our poly bags will decompose in a landfill much faster than standard plastic and can also be added to a home or industrial compost, where they’ll decompose in a matter of months.
Our dust bags are made from raw, unbleached cotton certified by the Better Cotton Initiative (BCI). They are also ideal for storing your cashmere. For more on storing, see the “Cashmere Care” section below or visit our Cashmere Care hub.
Limited Tissue Paper In Packaging
In 2019, we eliminated tissue paper from packaging whenever possible. While some of our more delicate items are still packaged in tissue paper for necessary protection, by eliminating it everywhere else, we've been able to save more than 500,000 sheets of paper (and counting) to date.
Recycled Paper Hang Tags
Our hang tags are made from 100% recycled paper, which is also biodegradable.
Cashmere has antimicrobial properties, due to the presence of lanolin. It is naturally breathable, wicks moisture, and has an odor-repellent quality, so you can wear it as many as 5 times between washes. In fact, washing too often can cause excessive pilling. Simply air out at least 24 hours after wearing, and before wearing again. The Laundress® Wool & Cashmere Spray is a great way to give your cashmere a quick refresh between washes, therefore conserving water.
When you do wash your cashmere, the number-one recommended method is to hand wash versus dry clean. Use cold water at 30° Celsius or less and a gentle detergent formulated for cashmere or wool. (We recommend The Laundress® Wool & Cashmere Shampoo, although baby shampoo works well, too. We have also tested Tangent GC Organic Sugar Perfumed Cashmere Detergent and loved the results; the garments smelled nice, maintained the soft hand-feel, and did not show any shrinkage or shape distortion after washing.) Do not rub or twist your cashmere when washing, but rather, gently swoosh the garment in a water bath to prevent deforming and excessive pilling. After washing, rinse gently. Finally, lay your garment flat on a clean bath towel and carefully roll the garment in another towel, then press gently to remove excess water before the drying stage. For more on washing, visit our Cashmere Care hub.
Pilling is normal for any natural fiber, including cashmere. Pills are the fuzzballs that occur on the surface of the garment due to friction. You can easily remove all of the pills and loose fibers by using a cashmere comb or a sweater stone (we love The Laundress® Sweater Stone), a pumice-like stone that glides over the garment without altering the unique surface. The pilling will lessen after removing the fuzz a few times.
Your cashmere sweater’s fabric is formed by inter-looping stitches, which have a natural tendency to grow. Therefore, proper storage is necessary. First and foremost: Do not hang your sweater to avoid growing (hanging your cashmere can also change shape of the garment over time). Instead, fold the cashmere garment before placing it in a dust bag and store in an airtight bin. The cotton dust bags White + Warren packages its garments in are perfect for storing your cashmere in; they are breathable, do not crash cashmere fibers, and are well-suited for storing in airtight plastic bins.We also offer individual dust bags for storing.. Additionally, folding your cashmere and storing it in a dust bag prevents moth damage. For extra freshness, toss in a sachet of lavender or cedar chips (avoid direct contact with the cashmere), which is nontoxic and a natural moth repellent.
