They say it fits even a large wrist but I don't think so. I have a pretty average wrist size and it barely fits. I installed it on the penultimate hole, and while it's comfortable and secure, I wish it was a little looser. The last hole is too close to the end of the strap, allowing its end to hang free and not slip under the lanyard, making accidental detachment much easier. Although the materials and construction are good, you might be better off looking for a different bracelet unless you have a below-average wrist size. Turns out the black stripe coloring tends to wear down the cuffs of the sleeves. Not ideal when wearing a white shirt.
