How comfortable are those Nike like bands?
I forgot to add— Apple Watch, Space Gray, otmake Black/Cool Gray band.
The band is an Apple knockoff and you'd know it if you held it and an Apple Sport or Nike band. It's thinner, lighter, and has a subtly different feel.
But I find it as comfortable as the Apple Sport bands. Being a copy of the Nike variant, it has more holes for the post, and the extra length tucking under the band provides a little more latitude than any other bands save the Milanese and Leather Loops.
All the holes provide decent ventilation, but if you work out fairly hard, it will trap some perspiration. It's very easily removed and is probably the fastest band to fasten. As a daily driver for casual/work wear, the Sport bands (and knock-offs) are my favorite.
Another small difference between this and Apple Sport bands is that the silicone doesn't stretch quite as easily as Apple's fluoroelastomer band and fits tighter over the post. Not a big deal at all, just something I observed.
