"I've been using the stick-on patches in my cycling jacket. Despite having good zip vents, I found that it only took a week of use for the jacket to start smelling a little unpleasant. Having stuck the tags inside the underarm vents, the smell is practically negligible.
"I think if my jacket had come with the tags already inside, there would never have been an odour problem. I can certainly say that they are a cost-effective and simple solution to a very common problem for cyclists."
