Mid Winter.
As cyclists, we always stumble upon one slight inconvenience in the winter. The end of your pants getting caught in the chainring problem.
I have always used the Snap Rolly, but I felt it wasn’t holding my slightly baggy corduroy pants enough, so I recently got the Magic Rolly and tried it for a few weeks and here’s what I feel about the two ankle bands.
Snap Rolly is best for : Spring, Summer and Fall clothes
Magic Rolly is best for : Winter clothes.
Of course, it all depends on the kind of pants you are wearing. I just thought the Magic Rolly was perfect for winter for me because I wear slightly loose pants with thicker fabric, such as corduroy.
Some of the models have reflectors on them as well, so you can be visible in the night.
