Organic Cotton Leggings & Flares

Looking to switch your plastic-based leggings for gorgeously soft, naturally breathable Organic Cotton leggings that are gentle on your skin? You're in the right place.

At Not Basics, we design Organic Cotton leggings for those who are tired of synthetic activewear and are looking for a more comfortable, natural alternative for everyday life. Made from 95% Organic Cotton with 5% elastane (required for stretch & recovery), our leggings are soft, breathable, lightweight and designed to move with you.

Whether you're running errands, doing light exercise, travelling, lounging at home or styling them for everyday wear, our Organic Cotton leggings are designed to feel as good as they look. The naturally breathable fabric helps keep you cool and comfortable throughout the day, while the high-waisted fit and gentle compression create a flattering silhouette without digging in – imagine it as more of a gentle hug vs the tight squeeze of a polyester activewear legging.

Choose from a range of bestselling styles including flared leggings, wrap leggings and foldover flared leggings in a range of our bestselling colours including black, brown, charcoal, blue and seasonal limited editions.

What are the benefits of organic cotton leggings?

When wearing clothing like leggings that sit close to your skin all day, it’s easy to overlook what you’re actually wearing. Organic cotton leggings are made from natural, breathable fibres that feel soft and gentle against the skin. Unlike many synthetic leggings made from polyester or nylon, organic cotton allows air to circulate more freely and helps regulate temperature throughout the day.

Many people choose organic cotton leggings because they feel less restrictive, more breathable, and more comfortable for long periods of wear – whether that’s working from home, travelling, lounging or everyday life. Organic cotton is also often preferred by those looking to reduce their exposure to plastic-based fabrics in their wardrobe.

At Not Basics, our leggings are crafted from 95% organic cotton with a small amount of elastane for stretch and shape retention, creating leggings that feel soft, supportive and naturally comfortable against the skin.

Are organic cotton leggings breathable?

Yes – one of the biggest benefits of organic cotton leggings is their natural breathability. Unlike many synthetic leggings made from polyester or nylon, organic cotton fibres allow air to circulate more freely, helping regulate body temperature and reduce that overly hot or “trapped” feeling often associated with traditional activewear.

Many customers choose organic cotton leggings because they feel lighter, softer and more comfortable for long periods of wear – whether that’s lounging at home, travelling, running errands, working from home or low-impact movement like yoga and walking.

At Not Basics, our leggings are crafted from 95% organic cotton with a small amount of elastane for stretch and comfort, creating a naturally breathable feel without the overly synthetic texture of many performance leggings.

What’s the difference between cotton and synthetic leggings?

The biggest difference between organic cotton leggings and synthetic leggings is the fabric composition. Most traditional activewear leggings are made primarily from polyester or nylon – synthetic, plastic-based fibres designed for high-intensity performance and compression.

Organic cotton leggings offer a different feel and wearing experience. Cotton is a natural fibre that is softer, more breathable, and often more comfortable for all-day wear. Many people find cotton leggings feel gentler against sensitive skin and less “tight” or restrictive than heavily compressive synthetic activewear.

Synthetic leggings are typically designed to be highly stretchy, sweat-wicking and squat proof for intense workouts, whereas organic cotton leggings are often chosen for comfort, breathability, lounging, travel, yoga, pilates and everyday wear.

At Not Basics, we designed our organic cotton leggings to bridge the gap between comfort and versatility – offering gentle support and structure without the overly synthetic feel of traditional activewear.

Are organic cotton leggings suitable for exercise or activewear?

Our organic cotton leggings are designed first and foremost for comfort, breathability and everyday wear. That said, many of our customers love wearing them for yoga, pilates, walking, travelling and light exercise both at home and at the gym.

Because our leggings are made from 95% organic cotton rather than synthetic performance fabrics like polyester or nylon, they offer a softer, more natural feel compared to traditional workout leggings. They are double-lined and non-sheer for everyday wear, but we do not market them as squat-proof high-performance gym leggings.

Ultimately, it comes down to personal preference and how you like your activewear to feel. If you prefer highly compressive, sweat-wicking performance leggings for intense training, synthetic activewear may be better suited. But if you’re looking for breathable organic cotton leggings that feel soft, comfortable and versatile enough for lower-impact movement and daily life, our leggings are designed with exactly that in mind.

Where are your organic cotton leggings made?

All Not Basics organic cotton leggings are made by our trusted manufacturing partner in Istanbul, Turkey.

Our manufacturing partner is both SEDEX audited, meaning they meet internationally recognised standards for responsible manufacturing, and GOTS Certified.

GOTS is the worldwide leading certification for textiles made from organic fibers – but beyond that, the certification mandates strict International Labour Organization (ILO) standards, guaranteeing fair living wages, no forced or child labour & safe working conditions.

Our customers say it best
I purchased the black, grey, red and green leggings and absolutely love them all. Just waiting for the chocolate to come back in stock and will be making another purchase. Absolutely love these for the days I don’t want to wear gym leggings but want to be cute and comfy. Massively recommend
— Laura
Bit sceptical initially but no regrets. Ordered 2 pairs of leggings initially and the red is my fave colour - I ordered size S and M and wear both but small fits me better. I’m returning customer as bought some tops and they’ve great too as quality material. Fully recommend this clothing range as good quality and really comfy.
— Jackie
I'm currently in the process of ditching all my polyester clothing for natural fibre clothing because of allergies and super sensitive skin. I have the full chocolate brown set from Not Basics (flared leggings) and absolutely love it! I get loads of compliments as it looks so chic and effortlessly elegant, even my dentist asked me where I got it from.

I love these products so much.. I’m in the process of gradually replacing all of my leisure wear and basics with them as the quality is so good and the fact that it’s organic cotton feels so good.
