I got the Alpine Loop band for my Apple Watch Ultra and, well, I immediately prefer this one to the Ocean band I initially got. Super comfortable, love the color, mechanism is great, and it's much easier to adjust. Recommended.
nate boateng@viticci It’s so great. @joshcalvetti has a couple that he dyed, and they look incredible.

Cory Nadilo@cory @boateng @viticci I just used the Rit synthetic dyes. I wound up combining colors until the solution looked about right, then I just submerged it for about 40m.
Rit tells you to boil the dye, but the hotter the solution, the more it shrinks the band. Honestly now that some time has passed, I wish apple would make an XL version of the band- dying brings the Large down to about a Medium, which isn't ideal, but hardly the end of the world. I think I kept the temperature about 130-140 °F.
@joshcalvetti @boateng @viticci Thx. Might try it on cheap amazon Alpine loops to test. Would not have expected the bands to shrink, that is good to know. No issues of the dye leaking out when cleaning them?
@cory Yeah, I think it's mostly the small amount of elastic in the bands that shrinks a bit. I did the blue one second and it was much closer to the original size than the purple- but hey, that's how you learn.
I’ve not had any dye bleeding out of them- I probably wouldn't try washing them with super hot water, but cold washing worked just fine for me. I took my pot and ran cold water into it from the sink until that water was all clear, then kept rinsing the band until it was clear as well
