Reddit reviews Mask - Econo 3 Weapon

It depends on the weapon. Eye protection is the most basic thing you need. Gloves are also quite useful as is a groin guard. Using a 3-weapon fencing mask is a good option for most not-too-sharp weapons.

For blunt weapons you could get away with something like this TKD helmet with a face cage. It's much lighter with better visibility than the fencing mask. It's good for just drilling head shots or something.

Not the top 3, but the rest of these look alright for weapons sparring. Make sure weapons gloves have a thumb cushion, and you can use more regular sporting gloves like lacrosse gloves, or sometimes cricket gloves although usually only one of the pair has thumb protection.

Racquetball goggles are good if you're just drilling and not sparring to protect against accidental eye pokes. Or these bad boys although mesh is annoying to see through.
