I said Lowepro Voyager C in use in conjunction with a Canon EOS 40D and the most 2.8 70-200 Body on it. Who has ever held in my hand, I know how difficult is such a combination.
The belt keeps both safe and has over other neoprene belts the advantage that it does not elongates large, that expands. Other neoprene straps on the market allow the equipment while running "bounce". This is not the case with this belt. The edges of the belt are clean stitched so that no chafing occur in the neck. The quick-release fasteners are very good and go on only if you really pressed both sides simultaneously. Unfortunately, the memory card case is to use only SD cards without the protective cover. But that would be too unsafe because here is where no complete tightness. For me this is more important because the Canon anyway has only CF cards.
So all in all a highly recommended strap without the lurid company logo, where the same raises thieves on the right track.
