Here you will find undergarments and basics made of organic cotton on the entire site—they even offer options for men, kids and bedding. Their panties come in all cuts and styles—the ones with lace always have an organic cotton gusset at the bare minimum. Pact is known for their commitment to help save the planet by making organic cotton affordable and accessible to everyone. Their philanthropic goal is their Give Back, Wear Forward initiative which allows you to donate gently used clothes that they distribute to nonprofits and then recycling the packaging you sent them in. Talk about sustainability. Plus, you can print out a free shipping label on their site to send in your donations.

1. Pact Classic Fit Bikini

From $14 at Pact

Pact has very high standards for its eco-friendly manufacturing practices and even has a Fair Trade certification, so you can rest assured the cotton used to make these undies was procured and woven in an ethical and sustainable manner. As one review says, “I have been buying PACT underwear for years because the cotton is organic and the fit is perfect. I bought so many pairs (and they endured so well) that I haven't needed to buy any since April 2017. I just came back to buy some basic black underwear, and I'm very glad to get those.”

2.  PACT Staycation Pajamas

From $38 at PACT

I’ve been wearing some variation of PACT’s cotton pajamas for about a year now and can attest that they are stretchy, comfortable and cute. PACT commits to using organic cotton and offsetting its carbon emissions. Additionally, the brand is Fair Trade- and GOTS- certified. I find that the shorts and short-sleeve tops are true to size, but if you opt for pants and long sleeves, I’d order a size down for a more fitted look.

3. PACT Loungewear

From $112 : $140 at Pact

PACT makes a slew of apparel from athleisure to intimates with organic cotton. The clothes are so comfortable, they converted Wu, who admits she’s never bought sweatpants or leggings in her adult life. “I’m NOT a loungewear person, but I haven’t been able to stop wearing a matching set I got from PACT,” Wu says. “The material is soft and thick without being suffocating, and everything is low maintenance—I throw it in the washing machine and the dryer.”

4. Pact High Cut Brief

From $54 : $39 at Pact

These briefs run a bit big, which can be helpful if you have a long torso. The elastic and hold are both light, so this wouldn't be an ideal pair for shaping or smoothing.
