Ok. I'm smart. Really, pretty over educated actually.
No matter what I do, I simply cannot find the leak in my exped pillow. I immersed it and can HEAR what sounds like a leak, but no bubbles anywhere (including out of the valve). I brushed it with some dr Bronners….no obvious holes. Yet it most assuredly is leaking, and kind of fast, too. It takes about 30 mins to completely deflate.
Any secrets I can try to find it? I know it's in there somewhere……
