I am wearing a pair of gloves from American Firewear that are made out of Kangaroo hide. In the last 33 years I have tried many gloves and these are probably the best pair that I have found for structural firefighting. They are a bit bulky but they are very flexible with good dexterity, provide good grip, easy to wash and care for, wet or dry they are easy to put on,(a huge plus in my book)and they have not yet gotten hard, brittle or stiff. I have worn them for 3+ years now and they are still in pretty good shape so I guess because of their durability they really aren't over priced at a hundred bucks a pair.
They are really good gloves I have them also, just watch though when they get really wet the little finger i believe it is pulls out some times.. Not sure if it may be the pair I have but when it happend it did it to both gloves..
