I like the lower profile and sleeker fit and look. The adjustment is not easy, but once done, you should be set for a while. My pup plays every day on a sandy beach along a salt water sound, and sand does not get imbedded, and it's simple to rinse and leave on a counter to dry. Great design, and first class materials. Don't count on controlling a squirming puppy, as it may pull off over the head (unless you have it too tight).
