I’ve been using this overlay for a couple months now and have come to really appreciate it. It’s more protective than the cloth or leather overlays, and tends to deflect more shots while being lighter. It’s rigid design breathes well and the back of head protection gas in the part that opens) is very good and extra padded at the back of the skull and neck.
I also have the Wukusi Cobra mask, and while I’ve never seen anything as protective as that, the Rattlesnake is a smart second. The Rattlesnake also has a key advantage: if the mask in the Cobra is damaged, you have to replace the whole unit. The rattlesnake, on the other hand, can switch between masks easily. For this reason, the rattlesnake has become my “daily driver”, so to speak, and is the mask/overlay I use most frequently. I reserve the Cobra for competition or intense training.
I would definitely recommend this overlay over the leather and cloth soft overlays. Also Velcro patches stick to it, which is kinda cool.
