Hi dking, our fabric bands and loops have a mix of nylon and latex. The bands only have a slight smell to them and most people will not notice the smell unless they hold the band right under their nose. Cathe has a sensitivity to latex too. When she uses latex resistance tubes her skin will have a reaction to the latex tube where it rubs against her skin, however, with the fabric bands and loops she doesn't have any problems when the bands touch her skin. This doesn't mean you will not have issues as everyone's sensitivity can be different, but none of our crew or staff, including Cathe, have had any issues.Hi, I am very excited about your new workouts! But I have recently developed a latex sensitivity. If a band has even a slight latex smell, I can't use it anymore. Do your bands and loops have any kind of chemical odor?
