So clothing for children needs to be extra-durable, not only to stand up to skidding into second-base at lunchtime kickball games, but also needs to be made from materials from which dirt and food can be washed out easily. They (hopefully) spend plenty of time outside and need outerwear that will keep the rain off and the heat conserved next to their body when it’s cold. At the same time, you may want to avoid clothes made with environmentally concerning chemicals. “Many mainstream brands have been shown to have hazardous chemicals in their clothing that can be absorbed through our skin," says Nadine Maffre, the editor of Zero Waste Memoirs. "Some of these chemicals have been proven to be hormone disruptors, are carcinogenic, or are damaging to your nervous system.” To top it all off, kids outgrow their clothing quickly, rendering investment pieces tricky. With all this in mind, designers who make kids’ clothing—and do it sustainably—often put a tremendous amount of thought and care into their products. Of course they want to make it cute and comfortable, so kids will pick it out of the drawer first, but they also want to ensure that it will last through normal wear-and-tear as well as staying in good-enough shape to pass it down to other children to use.

The company uses AZO-free dyes, and is dedicated to minimizing waste, using sewing-room floor materials in all kinds of projects, including creating clothing, masks and scrunchies made from smaller offcuts, to entire initiatives like quilts and throws that use them as patchwork pieces. Ace & Jig works with Project Thrive which employs at-risk women for special projects, and donates to a host of environmental and human-rights organizations each year. Best Designer: Stella Mccartney Kids View On Stellamccartney.com A member of the Sustainable Apparel Coalition, the designer brings her signature flair and ethical stance to her children’s line, which is filled with graphic, but still appealing-to-kids pieces. Many items are made from organic cotton and tencel, while coats and pants are made from a recycled polyester that’s fully windproof and waterproof (via a fluorocarbon-free coating).

The Best Sustainable Swimsuits of 2021 Best for Hand-Me-Downs: Hanna Andersson View On Hannaandersson.com Hanna Andersson touts that sustainability has been part of the brand’s identity since its founding in 1983. It has long used organic cotton, and not only are clothes designed to be worn by multiple kids, the company even provides name tags with several lines to promote and normalize the idea of hand-me-downs. The brand has the highest level of Oeko-Tex standards and is also GOTS-certified. As of this year, all outerwear including fleece and ripstop, is made from recycled materials. Best Splurge: Infantium Victoria View On Infantiumvictoria.com This PETA-approved German brand offers fashion-forward, vegan clothing for babies and kids. Each item has information about what fabric it’s made from (there’s a lot of GOTS certified cotton, but also a vegan wool too), as well as where accessories like buttons come from too. As part of the brand’s transparency commitment, the company also discloses where materials were grown and woven, as well as sewn and sold. There are also details about how much time each piece takes to make, in terms of paid work, and in which countries that work is done. The brand even has its own Preloved section for used items. Best Gender Neutral: Finn + Emma View On Finnandemma.com This brand offers a whole Gender Neutral section for those who aren’t looking for baby or toddler clothes that scream pretty princess or tough guy.

Even snaps are lead and nickel free, and all items are “heirloom quality” and meant to be passed down. Finn & Emma also carries fun, ethical accessories like a macrame swing, and stroller toys made from wood. Best for Winter Gear: Patagonia Kids View On Patagonia.com You'll find Patagonia on a number of Treehugger's lists of recommended products thanks to the gear company's efforts to manufacture sustainably and make clothing that lasts. Patagonia's gear for kids is no different, with durable designs often made with recycled materials and fewer "forever chemicals" that are often used to make outdoor waterproof. Some of jackets are insulated with recycled down, which isn't vegan, but does divert down feathers from ended up in landfill. Many of the garments are sewed in Fair Trade certified facilities. The company has sizing for babies and toddlers, so the littlest ones in your life can still hit the trail in the winter. Final Verdict We think the most sustainable option for kid's clothing is shop second hand, either locally or via an online retailer like thredUp. However, if you're looking to sock up on organic basics like socks and underwear, check out PACT Apparel's kids line (view on WearPact.com). What to Look for in Sustainable Kids' Clothing As Nadine Maffre says, there are many factors involved when it comes to classifying clothing as 'sustainable.' “We need to look at where the fabrics are coming from, how they're grown/made, where the clothes are constructed (and who is making them), transportation, how they're packaged, and of course, how well they're made,” Maffre says. Yes, this is a lot of things to consider and can seem overwhelming at first, but there are some short-cuts. Certifications There are some labels you can look for: When it comes to textiles, Fair Trade Certified; GOTS-, Organic, Cradle to Cradle, or Oeko-Tek certified; organic cottons, and wools; and recycled materials. Keep labor standards in mind too—kids in another country with poor labor laws and enforcement shouldn’t be making your childs’ clothing. “If clothing is very cheap, it's normally because someone is working for very little—often a long way from where you call home,” says Maffre. Quality “Focus on buying quality locally made clothing that's created out of organic fibers—do this and you'll be well on your way to supporting sustainable clothing brands,” Maffre advises. Because children will outgrow clothing so quickly and budget is a concern for most parents, consider “quality over quantity.” It’s easy to buy a five-pack of t-shirts, but does your child need five new shirts? What if you spent the same amount on two better-quality shirts or got t-shirts second-hand and put the money towards a good-quality jacket (that could be passed along and worn by others) instead? If you aren’t getting hand-me-downs from friends, checking out the kids’ clothes at a local thrift store or online group, and you do buy new clothing, avoid synthetic materials like polyester, acrylic and nylon. “While these fabrics are cheaper to produce, they're polluting our environment at an alarming rate, they use up non-renewable resources, and they're not biodegradable at end-of-life,” says Maffre. Of course, kids might not understand why they are not getting a haul of new clothes, especially if they see that behavior online or from friends. But a few more memorable and fun pieces will be more satisfying in the long run. “One of the main reasons we all need to have more of a focus on sustainability is to look after the planet that our kids are going to grow up in," Maffre points out. "That's a pretty motivating factor in itself!” Why Trust Treehugger? To create this list Treehugger tapped the expertise of sustainability writer Nadine Maffre about what to look for in sustainable clothes for kids. We then researched the manufacturing practices, ethics policies, and materials used by many kids' clothing brands to make a list of top recommendations.
