As a busy Mom of four who works from home, embracing comfort in clothing is essential for me. Leggings are my go-to everyday wear. During my exploration of various fabrics, I began to suspect that many of my existing leggings might not be safe for my health. It was clear that making the transition to natural fabrics would require careful consideration; I didn’t simply discard everything in a shopping spree for a new capsule wardrobe. Fortunately, I discovered some fantastic non-toxic legging brands, and I’m excited to share my top recommendations with you.

Understanding the Risks: What Makes Leggings Toxic? 

The risk of toxicity is particularly concerning when it comes to activewear due to several factors:

• When we sweat, our pores open up, creating a pathway for chemicals to enter our bodies.
• Synthetic materials can trap heat and bacteria, leading to skin irritation.
• The close and prolonged contact of leggings with our skin increases exposure to harmful substances.

Formaldehyde – This toxic substance is not only a known irritant for the skin and lungs but can also pose a cancer risk in high concentrations. It is commonly used in activewear to prevent wrinkles and stains.

PFAS (Per- and Polyfluoroalkyl Substances) – This group includes thousands of fluorinated chemicals, many of which have been associated with serious health issues, including a higher risk of cancer, reproductive harm, and immune system dysfunction.

Research conducted by Environmental Health News and wellness blog Mamavation revealed that 8 out of 32 pieces of activewear tested positive for PFAS. The majority of the tested items were workout leggings, which showed detectable levels of organic fluorine, indicating the presence of PFAS.

Heavy Metals – Commonly found in dyes and synthetic fibers, these can be absorbed through the skin, leading to various health problems. Lead exposure, even at minimal levels, can be dangerous, especially for women of childbearing age.

Phthalates – These substances are known endocrine disruptors that can elevate the risk of cancer, asthma, and allergies. They are often added to enhance the durability and flexibility of plastics, making them prevalent in polyester leggings.

BPA (Bisphenol A) – Some brands of athletic wear have been found to contain high levels of BPA, which can lead to several health issues, including asthma, cardiovascular problems, and obesity.

According to testing conducted by the Center for Environmental Health, some athletic wear, particularly leggings made from polyester and spandex, could expose wearers to levels of BPA that are up to 40 times above the safe limit according to California standards.

Key Features to Look for in Non-Toxic Leggings

When shopping for non-toxic leggings, prioritize brands that utilize sustainable fibers such as:

• Organic cotton
• Hemp
• Bamboo
• Linen
• Tencel
• Natural rubber
• Merino wool
• Modal spandex

Additionally, check for reputable certifications like:

• GOTS (Global Organic Textile Standard)

When examining care instructions, look for recommendations that include:

Washing in cold water, air drying, gentle cycles, avoiding bleach, and favoring natural detergents.

Seek out brands that are transparent about their manufacturing processes, adhere to ethical practices, and utilize low-impact dyes and finishes in their fabrics.

Review

This legging was the first one I received when I began my quest for non-toxic leggings, and it did not disappoint! What makes it so fantastic? It feels remarkably similar to Lululemon’s Align Leggings. If you know, you know! They are buttery soft and feel liberating rather than restrictive. Putting them on is effortless, unlike some leggings that feel tight and are challenging to wear. They do run larger than expected; I typically wear a medium, but I opted for a small with these. I did try the medium initially, and while they fit, I preferred a little more structure. I still wear the mediums as well, and they feel great! I’ve received numerous positive reviews from friends and followers who have purchased them. Many have expressed their love for these leggings, including my virtual assistant, who can’t stop raving about them! They are sleek, devoid of pockets or awkward seams, making them easy to dress up or down. The fabric composition is 93% TENCEL™ Lyocell and 7% Spandex.

Review

These leggings offer a feeling akin to Fabletics leggings, if that’s familiar to you. They fit snugly and provide excellent support. This can be beneficial, but they can feel a bit restrictive, especially around the midsection. Initially, they are somewhat challenging to put on and take off, so keep that in mind. I appreciate the sleek material that doesn’t attract much lint. However, due to their shinier appearance, they may not pair well with every outfit. I suggest sticking with your normal size, though you might consider sizing up for a more relaxed fit in the waist. They are made from 84% TENCEL™ Lyocell and 16% Roica® V550, and the OEKO-Tex certification is a significant plus!

Review

I enjoy how easy these leggings are to wear and remove, as they aren’t restrictive. Being made from wool, they remain breathable, making them excellent for workouts. They consist of 95% wool and 5% spandex. Their fit is more relaxed, so keep that in mind. During high-intensity workouts, I’ve noticed they tend to slip a bit at the waist, requiring adjustments. Their athletic appearance makes them less versatile for dressing up, but they are incredibly comfortable, perfect for lounging or strength training sessions. They generally fit true to size, although sizing down for a tighter fit is an option. The side pockets are practical without adding bulk.

I’m impressed that these leggings are crafted from hemp, cotton, and a touch of spandex. They have a rugged appearance, and while they felt a bit tight initially, they stretch comfortably. I reach for them for workouts and enjoy their breathability. They fit true to size and can also be styled casually. The inclusion of side pockets is practical but does not contribute extra bulk to the thighs, making them a staple in my wardrobe!

Review

Initially, I was skeptical about cotton leggings, but I was pleasantly surprised! They were a bit challenging to put on at first, but they stretch beautifully, just as I expected cotton would. I found myself enjoying them far more than anticipated! They have a sleek appearance and perform well for workouts, despite some visible stitching compared to the seamless design of Reprise leggings. The pockets are practical without adding bulk to the thighs. While they might be slightly see-through when stretched tightly, my partner said he couldn’t notice anything. Just thought I’d mention it for transparency!

Review

These leggings were my go-to for almost two years until I discovered the options mentioned above. I do like them, but I must say there are some aspects that could be improved. Firstly, they can be a bit see-through, so keep that in mind. I generally paired them with longer tops, which mitigated the concern. Also, they tend to be shorter in length, resembling cropped leggings. I wish they were a tad longer, which may not be an issue for shorter individuals, but I’m 5’7”. They’re comfortable and great for relaxing at home, made from 92% Organic Cotton and 8% Spandex, and fit true to size.

Review

These leggings are my least favorite among the options available. I purchased them three years ago while transitioning away from plastic leggings. They were quite long, leaving me with extra material, and they wouldn’t stay up at the waist. Additionally, they lacked a flattering fit. Overall, they just didn’t meet my expectations regarding comfort and style.
