Hi, future TK Member!

Want to help us build a more sustainable future?

A membership that puts the future in your hands

What if the way you buy could change everything? Together, we can build something totally new.


We know that our economy just isn’t built around sustainability — it’s designed to exploit resources for profit.

Call us dreamers, but we think we can do it differently.

Meet the TK Membership Program. We’re moving toward a fully member-funded production model, so that we make only what we need: no more, no less.

We’re asking you to join the team. 

Help us build a retail ecosystem that serves all of us — not just big corporations. Become a TK Member and choose community over consumerism.

Reasons to become a TK Member:

For You:

  • Free Basewear set 

  • Shop TK with 20% off regular products

  • Priority status on all new Basewear pre-orders* (Members are automatically opted in to pre-orders!)

  • Members-only access: exclusive inventory & limited releases, as well as sneak peeks of all new products

  • First dibs on the semi-annual Secret Gear Sale 

  • Get your Basewear repaired whenever you need it
    (Basewear Repairs is open exclusively to TK Members!)

For Us:

  • Tell us how much to produce when we’re making new products — so that we can predict inventory needs

  • Support our small, women-run, grassroots brand

  • Help us fund new product releases

For the 🌎

Help us reduce waste and fight overproduction


Because we’ll know exactly how much of a new product to order and in what sizes, TK Members help us to create only what we need.

Hey, we’re TK!

No big corporation here. Tera Kaia is a grassroots, member-supported business based out of the Eastern Sierra. Our team facilitates the creation of small batches of ultra comfortable underlayers for everything you do: from swimming to hiking to simply hanging out on the couch. We’re known for making the only sports bra you’ll ever want to own.

What Members are saying:
What Members are saying:
“Took a chance on becoming a member before I'd even tried out any TK Basewear, and I'm already loving it. I received my first set quickly after joining and immediately tested the bra out on a run — I have never worn such a comfortable sports bra! Can't wait for the next batch to arrive!”
— Kerry M., Norfolk, VA
What Members are saying:
“The membership is a great deal. You get your money's worth with the initial shipment and early access is imperative because they sell out so fast!”
— Jamie H., Kaneohe, HI
What Members are saying:
“This is an amazing way to support a fabulous company. I love getting the pre-order and being able to choose which items, if any, to purchase. I also really like the concept of funding the production of the order and helping to reduce an abundance of surplus or waste.”
— Jane L., Manchester, NH

Frequently Asked Questions:

What does my membership get me?

A front-row seat to all things TK, for less than a set of Basewear!

Our members get a free set of Basewear when they sign up, plus discounts, perks, and the ability to influence what products we make! Our community helps us make important decisions like new colors, new products, and more. 

Oh, and you support the longevity of Tera Kaia and help fight overproduction by imagining a totally new kind of retail ecosystem with us — aka the coolest thing on the planet, for the planet.

What is the member community like?

We send our members exclusive, behind-the-scenes content in our newsletter. You’ll be the first to know about all things TK! 

We also go to our members for feedback and input about what we should make next — new colors, new products, and more. Our members are more than just customers; they’re TK, too!

Our membership program is still new! Let us know what you’d love to see. We 🩷 hearing from you: orders@terakaia.com | hello@terakaia.com

Is there an annual fee?

Nope! Your one-time purchase gets you in — forever! 

What does “automatically opted in to pre-orders” mean?

As part of our new retail model, our members have essentially raised their hands and said, “I expect to buy new releases from Tera Kaia!” Sometimes, those products will only be released to members. 

We keep your card on file and automatically consider you to have pre-ordered new releases. Unless you let us know that you want to opt-out of a particular release, you’ll be charged and sent the new product once it’s ready to ship! 

We consider our members to be a crucial part of both our product development and inventory processes. We keep our members in the loop and notify them about upcoming new releases. The automatic opt-in helps us understand how much of each product we should make, which lets us create only what we need: no more, no less.

What if I don’t want this season’s pre-order?

Want to opt out? No problem. You’re not obligated to order new releases; we’ll send along a reminder to let us know during the grace period.

Welcome to
TK’s future.

Our mission is to produce functional garments that fit real women’s bodies without compromising our values of slow, small, ethical production. We want you to come along for the ride.
