Field Test Shirt Pack

Our mission, to be Better Than Yesterday, fuels everything from our workout plans to our product development. That means we’re in a continuous state of development and always researching new ways to deliver the highest quality gear. The Ten Thousand team and our athletes are constantly trying new fabrics, tweaking fits, and testing new features. And for some of our latest shirt fabrics, we want a lot more feedback – so we wanted to work with our customers to really put these options through a scaled wear test.  

With a Field Test Shirt Pack, you’ll receive four prototype shirts to put to the test. After you put the shirts through the wringer, we’ll reach out for feedback – and that feedback will help inform how we continue to expand and improve our gear.

To show our commitment to constant improvement, these shirts are being sold at cost – no markup, no profit. With this limited edition collection of just 500 packs, our number one priority is to work with our community to test new products to make sure they exceed your needs and expectations. Let’s build something better, together.

UPDATE: The Field Test Shirt Pack has fully sold out. Thank you for the support, and stay tuned for more exciting product launches. We're looking forward to doing even more collaborative product work with our community.

How it works

Grab a pack

Order a Field Test Shirt Pack, and you’ll receive four different shirt prototypes. From ultra-lightweight to ultra-durable, these shirts will cover the full spectrum of materials, design, and functionality. In addition to the shirts, you’ll also receive a free hat.

Put it to
the test

Crush your WODs, get some punishing lifts in, and take them on your runs. No matter how you train, it’ll be time to put these shirts to your test. Don’t hold back: the best way to figure out if something works for you is by pushing it to its limit.

Give us your

After you’ve spent time training with the four shirts, you’ll share your feedback with us. We’ll send you a survey, and you’ll give us your lowdown on the shirts. This is where you truly get the chance to shape the future of our product offerings.
