Please refer to the image below to check the tag dimensions before you buy. 

When we designed our SOS tags we did apply them to many of the most common designs helmets to ensure they were ‘fit for purpose’. This includes some of those cycle helmets that are made of holes and give you very little room to work with. We’re confident you can fix our tags to just about any helmet, and the adhesives we use are high quality and helmet friendly.

If you find one you can’t fit a tag to, do let us know as we’d be interested to learn about that.
