I've got a Delta Mike snood, the mk.2 version. Only run it out once so far but it was a very close quarters, sweaty environment and it was great. Comfortable and easy to slip on/off between games, good amount of mesh to protect the teeth.
One thing to note is that the mk.2 has a slightly bigger mesh area than the mk.1, so it offers a bit more protection for the lower face. That being said, depending on how big your shnoz is, it doesn't provide much nose protection really, and the cheek areas are only protected by the lighter breathable mesh material of the mask, the metal bit only really protects your mouth/lower nose area. All in all its a great piece of kit though for the price.
I've also seen people rocking those NB tactical masks but they are a rip off in my opinion. 80 quid including postage is mad just for a face mask. Believe it or not, I found an amazon seller selling the NB tactical 'ghost' balaclava for 5 quid, compared to the 20 they're flogging them for on their website. I snapped one up and was thinking of pairing it with a standard mesh mask for the NB tactical look and performance... at a tiny fraction of the cost
