Ihave a USIA drysuit. Is the farmer john underwear with the jacket too much float???I need fourty pounds to get down and have a tough time staying at 15-20 feet on the way up. What gives? the underwear is USIA issue.

It would depend if you were talking about fresh or saltwater diving and how much you weigh. In my experience I have to wear 36 to 42 pounds in fresh water and I weigh 205. I am on a local dive rescue team and all of the team members will wear the 42 pounds to make sure that we stay on the bottom when we are doing a rescue. Some of the team members have said that they have a hard time in the 15-20 foot range like you are talking about but we found that if they used some older underwear that problem seems to go away. So you might try adding a pair of ankle weights and as the underwear gets older you might try removing some of the weight. Sorry that I can’t help out any more but I don’t think that is too much weight unless you are having a hard time with the drysuit not giving you enough lift when you are wearing the 40 pounds.
