I have used MSA Firehawk with 2 departments and I love them. They are easy to don/doff and to hook up to air. One other thing I like is that they use very few batteries and they are easy to change when needed. One of our neighboring fd's uses another brand (can't remember which) and they have all sorts of problems with batteries and hooking to air. We have a couple new members and they like MSA much better than the other ones.
