Way smaller than expected.
I tried both the small and the medium and they were both way too small. I have a 28 inch rib cage and even the medium I could barely fit on the biggest setting and there was not enough play in the elastic for the shoulder straps . I’m disappointed, they seemed like a good design otherwise. To be honest, I’m not entirely sure the medium and small were even different sizes as I returned the small then ordered the medium so couldn’t directly compare. I did not try the large given there was so little difference between the small and medium.
