Three rules before you compare
- 01
The current organiser’s prohibited-items and bag-size rules override every generic packing list.
- 02
Choose equipment that still works after rain, queues, security checks and a full day on foot.
- 03
Test fit, charge and weatherproofing at home; race morning is too late to discover a weak link.
Shortlist
Product families worth checking
01 · 3M PELTOR or equivalent
Rated over-ear defenders
Best for: Simple, visible protection
Earmuffs surround the ear and are easier for many spectators to fit consistently.
Confirm the regional rating, seal around glasses and correct child or adult fit.
02 · Certified safety brand
Rated disposable or reusable earplugs
Best for: Compact backup protection
A correctly inserted plug is easy to carry and can back up earmuffs.
Learn the fitting method before arrival and never share reusable plugs without cleaning.
03 · Rated specialist brand
Flat-attenuation musician-style plugs
Best for: Preserving more event sound
Some protective devices reduce frequencies more evenly while still providing rated attenuation.
Do not rely on marketing words; verify the published protection rating and fit.
