Amazing, comfortable, no irritation. I have very sensitive skin and almost all watch bands I have used have left rashes or soars on my wrist. Even loose bands (which makes the heart rate sensor useless) often create irritation with me. I have tried various metals, fabrics, and plastics to no avail. The canvas watch band has been stellar in this regard, I can wear it tight enough to use the heartbeat sensor and 1 month in, no irritation. The fact that it is machine washable too makes me confident that with the appropriate care this will not be a problem for the life of the band.
