Sharing is caring!

Underwear. They’re a fact of life. But most of them aren’t made of particularly eco-friendly or comfortable materials. So what’s a girl to do when she’s constantly on the go or hitting the trail on her next epic adventure or even just lounging around the house? Fill that underwear drawer with the most comfortable and sustainable underwear for women that she can find, that’s what. We’ve even done the legwork for you and researched some of the best of the best in that department. So read on and, when it’s time to replace the old for the new, try these on for size.

Comfortable & Sustainable Underwear for Women

boody sustainable underwear for women
Boody Shaper Bra


Made of super eco-friendly bamboo, Boody’s entire line of sustainable underwear for women, including loungewear and even athletic wear, is silky soft and super comfy. Their underwear comes in just about every style you could want, from boy shorts to bikini briefs (as well as options with less, ahem, “coverage”…). As for bras, you won’t find any wires here (cue Mendell’s Hallelujah Chorus). There’s a sports bra, lounge-style shaper bra, and padded shaper bra that has the potential to become you day-to-day go-to. Find women’s bamboo underwear here and bamboo bras here.

Why is bamboo sustainable? For starters, it doesn’t require irrigation, pesticides, or herbicides, plus it grows so quickly it’s considered a renewable resource. And it produces, too. An acre of bamboo yields about 150 tons of usable material while cotton only yields about 3-5. So get your bamboo on!

Patagonia sustainable underwear for women
Patagonia Sender Briefs


Patagonia is known far and wide as a leader in the outdoor industry when it comes to sustainability. And lucky for us, they make more than outerwear and duffle bags. Their women’s underwear and bras are super soft and vary in style and support from sports bras to loungewear to activewear.

The Sender Briefs, for example, are made of moisture-wicking recycled nylon and spandex mesh for high-output adventure activities while the Barely Everyday Bra is made from partially recycled nylon and spandex for supreme comfort. Find the other options on REI.

MeUndies sustainable underwear bra

Based in California, this brand makes almost all of their women’s (and men’s) underwear out of MicroModal, a brand name for lyocell (read about what lyocell is and why it’s sustainable in this article). But for now, here’s what you need to know: it’s sustainable and super soft.

They make men’s underwear, too, but the offerings for the ladies include underwear in several styles for all body types plus several bra options. Sure, there are basic colors for everyday wear, but colors and patterns abound (including dinosaurs!!), so have some fun with it. Extra plus: they’re all super comfy.

They’re available in classic colors (plus a few vibrant options), come in all your favorite styles, and don’t contain pesticides or petroleum-based synthetics. But our fave thing about the brand? They’ll recycle your old underwear–yes, any brand–and send it off to be turned into insulation! How dope is that? They’ll even provide the shipping label (and reward you with a free pair of undies in your next order)! Order yourself a pair (or a whole custom box) here! Update: Knickey now also has a whole line of super high quality and super comfy organic cotton bralettes! Your boobs need one (or three). Find them here.
