For most styles either MaxiGuard or EconoGuard for full protection. CoolGuard is great for light sparring or fitness training or heavier styles if using the new Super inserts. For the non contact styles CoolGuard may offer sufficient protection with the standard plastic inserts.
Paintball / Skirmish
MaxiGuard is great. The "hits" are easier to count and no pain!
Soccer or Rugby
The CoolGuard is designed to be worn in the many other sports where some contact to the breasts can occur and where the MaxiGuard could be too hot if the sport is of longer duration than Fencing or Martial Arts. The new Super inserts are great for all sports. Many women use CoolGuard in Basketball, Netball, or as additional protection in Hockey and Lacrosse.
