I have used the Debeer Icon. I love it. It does not have bulky padding and is really low profile. It is also very cheap ($40 or less).
The best on the market as of right now is probably the eraser but it is a bit on the expensive side ($70+). But many goalies use it and it does not have a lot of bulky padding.
One that I may try is the Sentinal. It does not seem to have a lot of bulky stuff and looks protective. It is mid range ($50+).
Look on
