@harrismasket thanks for reaching out about your ground pad, and sorry to hear it's leaking air.
Although we don't repair ground pads, we have a helpful article on how to do such repairs and sell the types of items you'd need to repair the most common reasons they leak. Replacement of your ground pads would be subject to our 1-year return policy, something you can follow up with at your local REI store once they are open for in-store shopping and returns. Hope this helps!
Replace it with a closed cell foam pad. They don't leak.
