I think hoot Gibson's are made of fire hose ? Anyone?
i love his collars, they will never get cut through, but are a little heavy. very good price too.
i quit runnin' flex collars because they flex too much. if you have a 4" collar, sometimes you get 3" on the bottom or top depending on where it flexes. they are very light though and allow a dog to move better, but ive had a few dogs get cut under the collar where they wouldn't have if it would have been a stiff 4" all the way around.
