Natural Fiber Clothing & The Pros Of Cotton Underwear vs Nylon

| 0 min read

When searching for kids clothing, price point is a top priority.

This makes sense since kids grow so quickly, but cost accessibility shouldn’t be the only thing we value as parents. We should also be putting an emphasis on searching for natural fiber clothing and working toward welcoming less synthetic clothes into our kids’ wardrobes.

Often, we forget what synthetic actually means, since marketing has told us it equates to innovative fabrics or textiles that offer moisture-wicking technologies. The reality is synthetic fibers are derived from fossil fuels. Considering that our skin is our largest organ and the most absorptive, we suggest choosing natural fibers first, whenever possible. Natural fibers are also generally healthier for the planet, considering that they can more easily biodegrade and go back to the earth at the end of their life.

In reality, finding alternatives to synthetics can sometimes prove challenging since over 60% of global fiber production today is synthetic materials. At the same time, there are great cotton and natural fiber options in the market.

Here’s some tips to keep in mind when searching for clothes that are not synthetic:

  • Always check labels in person or review the fabric composition online (companies are required to disclose this information)
  • Search for *100% cotton* clothing when searching online  

We recommend making one swap at a time to help shift your kids’ wardrobe from synthetic options to more natural fiber styles. Here’s some of our top swaps to get you started – 

Swap Cotton Underwear In For Nylon Or Polyester Options Instead of polyester underwear, choose 100% cotton or 100% organic cotton underwear. The pros of cotton underwear vs nylon are extensive, and they are always a better bet for kids with skin sensitivities. From boxer briefs to boy shorts to briefs to organic options, our underwear lineup is extensive and made with soft baby rib cotton that’s knit and dyed locally in Los Angeles, California.

Reach For Cotton Leggings Instead Of Synthetic Versions The majority of leggings in the market are made with synthetic materials like polyester or nylon. Even if leggings are made with cotton, they usually have at least 5% spandex in their composition. Synthetic vs cotton leggings? We always reach for cotton leggings that still offer a good amount of stretch and are better for skin sensitivities.

Choose Cotton Athletic Wear Over Nylon Or Poly Styles When our bodies sweat, our pores are open, making our skin even more absorptive than it already is. This fact alone leads us to choose natural fibers over synthetic for athletic wear. While your kids might have to wear the polyester or nylon team uniforms that are provided, we recommend considering cotton styles for practices and play. For example – instead of synthetic athletic shorts, search for 100% cotton shorts that are soft, comfortable and breathable. Added bonus? They don’t stink when they get wet and some cotton options actually have UPF 50+ sun protection.
