I 2nd the recommendation for the Mako rubber belt with tin man weights. Knives / Lights / Weights & Belts / Accessories I wear the belt under my crotch strap and it will pull free should it need to be dropped. The belt is absolutely secure on the waist and the rubber provides good friction to the drysuit so the belt never sags or moves during a dive. This is by far the best weight belt I have ever used and I've tried a few.I have a Mako rubber belt with the tinman weights and I absolutely love it. Also, those guys at Mako are very military friendly, so that's a +2 in my book.
