9 Organic Cotton Sweatpants Sets For 2024 (Reviewed)
The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.
I wore these organic, nontoxic cotton sweatpants and sets everywhere, from lounging at home to the farmers market. Here’s what I thought.
Saying yes to the loungewear trend is easier than ever, especially as the days grow shorter and the weather gets cooler. So it’s no surprise that we’ve got our eyes on snuggly sweatshirts and sweatpants for ourselves and our loved ones this holiday season. (Because who wouldn’t want to be MORE cozy and comfortable?)
These brands combine style and comfort with sustainable fabrics and ethical production practices. Many use organic, recycled, or responsibly sourced materials, and some offer inclusive sizing and collections for all genders and ages. That means you can wrap up your parents, partners, and loved ones in quality sweats that make for less eco-impact and more lounging.
Why consider organic cotton sweatpants and sweatsuits?
Organic cotton is better for our health and the environment compared to conventional cotton. Since organic cotton is grown without synthetic pesticides or fertilizers, it reduces environmental pollution and promotes healthier soil and ecosystems. This sustainable farming method conserves water and supports biodiversity. Additionally, organic cotton farming often involves fair labor practices, ensuring better working conditions for farmers. And when it comes to our health, organic sweatpants are typically softer, less likely to cause skin irritations, and — due to the brands dedication to crafting sustainable garments — generally better quality (meaning they will last).
Our criteria and methodology:
I personally tested each of the brands on this list, making notes about the fabric’s comfort (no itchy tags!), breathability, and polish for wearing out and about. I’ve also noted below the brand’s certifications ensuring they’re safe for you and the environment. We update this list regularly with our emerging favorites that meet the following criteria:
ORGANIC | All of the brands below use organic cotton that is super soft and never treated with harmful chemicals, and have the certifications to back this up.
SUSTAINABLE | Each brand is committed to various sustainability initiatives to ensure a low impact as well as ethical production practices. Again, I’ve noted the certifications that ensure this.
COMFORT | I’ve tested these from my couch, bed, and WFH desk, noting their breathability, softness, cut, and other elements that make them easy for all-day wear.
STYLE | Many of the brands below are polished enough for errand runs, school pickups, and airport fits.
If you’re looking to upgrade your full WFH look, don’t forget house shoes and slippers—oh, and a robe for those extra chilly days.
Best Overall | Best Luxury | Most Size Inclusive
1. Pact
Best For | Loungewear sets
Price Range | $58–$98
Size Range | XS–3XL
If classic cotton is your go-to for loungewear, Pact is the brand for you. Ethically made from GOTS certified cotton in a fair trade factory, all of Pact’s sweats and loungewear are as sustainable as they are cozy. From slouchy, oversized hoodies to slim-fit joggers, the brand is bound to carry the style for you in your comfiest fit. I have been living in the thermal waffle collection—the colors are perfect for fall. I love the joggers, but they also come in wide-leg!
2. MATE the Label
Best For | Sweatshirts and zip-ups
Price Range | $205 (crewneck)–$235 (sweatshirt)
Size Range | XS–3XL
It’s no secret that I’m obsessed with MATE the Label (read my full review here). I have been living in the half-zip fleece since summer, and I can confidently say it’s continued to be my go-to sweater into fall. Each piece in Mate‘s sweatsuit collection is ethically made in Los Angeles, where it’s cut, sewn, and packaged with a minimal carbon footprint. Even better, these stylish and sustainable loungewear staples are made from organic cotton and then dyed with non-toxic, low-impact dyes. As for sweats, I love the wide-leg pants, especially on my shorter legs. They fit just at my ankles and the pockets are so deep and cozy!
3. Girlfriend Collective
Best For | Recycled sweatpants
Price Range | $78
Size Range | XXS–6XL
One of our favorite activewear brands, Girlfriend Collective, also makes some of our favorite rest-and-recovery pieces! While these are not organic cotton, they are made from recycled fabrics in fair wage facilities, and we love GC for its continued dedication to size inclusivity (up to 6XL). I personally find these sweats to be absolute perfection in terms of comfort, softness, and fit. They are reminiscent of the classic Hanes sweatpants but more sustainable and way better quality. Oh, and no butt sag, either!
4. Reformation
Best For | Fashion-forward sweatpants
Price Range | $68–$148
Size Range | XS–XL
For a sweatsuit that is a bit edgy and fashion-forward, I love Reformation’s Austin Zip Up and Skye Boyfriend Sweatpant. It’s cozy yet fitted, and the ankles aren’t as tight as your typical sweatpants or jogger, which gives these a unique look. The cropped zip-up also has a hood (love!), making it extra cozy for lounge days, napping, or wearing on a plane. Reformation uses 100% organically grown cotton and the Los Angeles-based brand creates products only from sustainable and upcycled materials in a fair wage environment.
5. Reprise
Best For | Matching sweatset
Price Range | $95 (sweats + sweatshirt)
Size Range | XS-4XL
We are so excited to have discovered Reprise, a woman-owned brand dedicated to creating clothes with nontoxic plant-based materials. I recently tried the brand’s compression leggings, which are made using a clean and regenerative fabric, and so I knew I had to try out the organic cotton sweatpant set for fall. It’s made with GOTS certified organic, ultra-soft cotton fleece with a cozy brushed interior and produced in a windmill-powered, Fair Trade Certified™ facility. It’s unisex, too, and the Ivy color is perfect for a comfy streetwear look you can pair with sneakers.
6. Kotn
Best For | Classic organic cotton sweatpants
Price Range | $80
Size Range | XXS–XXL
If you’re seeking the best in cotton quality and searching for a brand that prioritizes ethics and sustainability, then you’ll love Kotn for its collection of premium basics made for all genders. This brand partners directly with family-run farms in Egypt and Portugal, where sweats are sewn using cotton-based fabrics and where everyone — from the farmers to the local weavers — earns a fair and living wage. I have been living in Kotn’s Essential Sweatpant since I received it (in minimal paper packaging, to boot). The racing green color is so flattering, and I love how these bunch perfectly at my ankles. They remind me of something I’d have worn in high school in the 2000s (in the very best way)!
7. Organic Basics
Best For | Wide-leg sweatpants
Price Range | $44–$78
Size Range | XXS–XL
Organic Basics makes our kind of basics — comfy, sustainable, and effortless. Crafted from 100% organic cotton, the brand boats a lot of fun and current styles, like wide-leg pants and terry sweats for a vintage look. Organic Basics also prioritizes ethical production and uses only recycled, recyclable, and organic materials in their clothing for minimal waste and impact. I tried two styles from the brand: The True Knit Wide Leg and the Weekend Straight Leg Sweats. Both are so cozy, and I love the wide-leg fit for comfort. I will note the True Knit pants are a bit long for my shorter legs (I’m 5’3″), but I could see myself dressing them up with boots for a cozy fall lounge look.

8. Harvest & Mill
Best For | US-grown organic cotton joggers
Price Range | $118
Size Range | S–XL
Is it possible to fall in love with a pair of sweatpants? Because Harvest & Mill‘s joggers are seriously dreamy. And it’s no surprise either since the American-made apparel uses only USA-grown organic cotton with low-impact and natural dyes. The jogger-style sweatpants are incredibly soft and airy, making them perfect for transition seasons and warmer fall or spring days. I love how tailored these fit, so I can easily dress them up or down, too. If I had to pick a pair of sweatpants that are perfect for vacation or travel days, these would be the ones.
9. Quince
Best For | Fleece joggers
Price Range | $35
Size Range | XS–XL
While not organic cotton, Quince’s fleece joggers are so soft that we had to include them on the list! They are made using GRS-certified poly yarn (68% Tencel™ modal, 27% recycled polyester, 5% spandex), which diverts plastics from ocean and landfill, and we love how budget-friendly they are. Quince also uses eco-friendly dyes for reduced water consumption. I tried these in heather grey for sweatpants that are natural enough to dress up or down. I love that they are fitted enough that I can wear them for errands and not feel like I’m wearing pajamas, but cozy enough that I can lounge in them (or even sleep in them!). The pockets are nice and deep too, which is a huge perk on my list.
