I recently purchased one of the new Nike Sport Loops after having had three of the regular Apple ones, but had to return it the next day as it gave me a rash. The same thing happened with the trail loop last Christmas. I’ve worn plenty of other nylon watch straps over the years and never had any issues. I was wondering if anyone else could we the regular Sport Loops but struggle with the Trail Loop or the new, or previous, Nike Sport Loops. Seems very strange and other than the Sport Band I’ve never had any issues.
