What is the liner?Updated 2 months ago

It’s one of the things that makes birddogs…birddogs.

Our built-in liner is designed to give you support without the squeeze. It replaces your underwear and makes everything more comfortable — no chafing, bunching, or swampiness. Plus, every pair is made with breathable, stretchy fabric so you can wear them all day, anywhere.

The liner moves with you, keeps everything in place, and stays cool no matter what you’re up to. Whether you're walking, running, lounging, or living your life, it’s engineered for all-day comfort and zero distractions.
